Carbon dioxide conversion to synthetic fuels using biocatalytic electrodes

Carbon dioxide has evolved from being considered as a greenhouse gas to a valuable carbon feedstock for the generation of artificial fuels and valuable chemicals. In this work, we review the biocatalytic approaches towards CO2 conversion into chemicals and fuels. We display the opportunities and challenges of using biocatalysts. Our work especially focuses on bio-electrocatalytic systems. These electrochemical applications of biocatalysts gain increasing interest, as electrochemical redox processes can avoid expensive mediators and co-factors. This is also a pathway for renewable energy storage because wind or solar energy can possibly be applied as electrical sources for the electrochemical CO2 conversion systems. Biocatalytic CO2 conversion together with renewable energy storage represents a viable and sustainable route for the generation of chemicals and fuels.

Effect of trifluoromethyl substituents in benzyl-based viologen on the electrochromic performance: Optical contrast and stability

Viologen (V) based molecules are classic and prestigious electrochromic (EC) materials which have dramatic optical contrast and tunable coloring states in solution-type electrochromic devices (ECDs). However, the stability of viologen based ECDs was significantly reduced by the dimer formation, and the resultant aggregation of viologens, which may occur once viologen dication (V2+) was reduced to viologen radical cation (V+?). To diminish this phenomenon, two novel symmetric benzyl-based viologens including 1,1?-bis(3,5-bis(trifluoromethyl)-benzyl)-4,4?-bipyridine-1,1?-diium (DTFMBzV) and 1,1?-bis(4-(trifluoromethyl)benzyl)-4,4?-bipyridine-1,1?-diium (TFMBzV) with various numbers of trifluoromethyl (CF3) substituents were synthesized and studied in this work. Substituent of CF3 in benzyl-based viologens not only enhance its optical property by increasing the pi?conjugation of bipyridine, but also avoid the aggregation by repulsing the viologen with fluorine atoms. The electrochromic performance of ECDs consisted of benzyl viologen (BzV/Fc ECD) and benzyl-based viologens with various numbers of CF3 substituents (DTFMBzV/Fc ECD and TFMBzV/Fc ECD) incorporated with ferrocene (Fc) were studied. According to the result of UV?vis absorbance spectra, the absorbances of benzyl viologen-based ECDs were strengthened at 399 and 605 nm by increasing the number of CF3 substituents. The DTFMBzV/Fc ECD gives a high transmittance change (DeltaT) of 63.5% at 605 nm initially with a short response time (<3 s) by biasing the cell potential from 0 to 1.1 V. As for the stability, the DTFMBzV/Fc ECD exhibits an extremely high retention (97% of its initial DeltaT) after switching for 10,000 cycles, which implied the dimerization of viologen was diminished by introducing the CF3 substituents with stronger electrostatic repulsion. As the result, DTFMBzV/Fc ECD exhibited the best electrochromic performance in terms of optical contrast and long-term stability. This study provides a simple yet effective strategy to tailing the electrochromic properties of viologen molecules for further application in electrochromism.

The Importance of Hydrophobic-Hydrophilic Factors in Binding of Charged Substrates to Micelles: The Use of Extramicellar Probe Luminescence to Monitor Association of Cations to the Micelle

The anionic metal complexes 1, RuL34-, where L = 4,4′-dicarboxy-2,2′-bipyridine, has been used as an extramicellar lumeniscent probe to monitor the binding capacity of anionic sodium dodecylsulfate micelles for the quencher Cu2+ and several organic cations.Addition of surfactant attenuates the quenching activity of the cations toward 1 in each case.For Cu2+ the binding capacity, as monitored by the quenching of the extramicellar probe, is in good agreement with those determined for Cu2+ and other divalent metal ions, using quite different methods; curvature in the quenching plot as increases is attributed to screening of the micellar charge by bound Cu2+.For MV2+ quite different behavior is observed; the Stern-Volmer type quenching plot shows two good linear portions at any surfactant concentration.The portion with low slope at low is attributed to MV2+ binding to the organized surfactant; at higher the steeper plot has a slope essentially the same as that obtained in water in the absence of micelles.The absence of curvature suggests association of several MV2+ molecules does not inhibit binding of additional quenchers until nearly all the binding sites are occupied.This finding, combined with the relatively high binding capacity in terms of cation/SDS for MV2+ compared to metal ions, suggests that MV2+ binds at different sites and that other factors control its binding.Similar results heve been obtained with other organic cations.The results are most consistent with a model whereby these bind at hydrocarbon-water interfaces and not primarily with the micelle head groups.

Functional Complementation Studies Reveal Different Interaction Partners of Escherichia coli IscS and Human NFS1

The trafficking and delivery of sulfur to cofactors and nucleosides is a highly regulated and conserved process among all organisms. All sulfur transfer pathways generally have an l-cysteine desulfurase as an initial sulfur-mobilizing enzyme in common, which serves as a sulfur donor for the biosynthesis of sulfur-containing biomolecules like iron-sulfur (Fe-S) clusters, thiamine, biotin, lipoic acid, the molybdenum cofactor (Moco), and thiolated nucleosides in tRNA. The human l-cysteine desulfurase NFS1 and the Escherichia coli homologue IscS share a level of amino acid sequence identity of ?60%. While E. coli IscS has a versatile role in the cell and was shown to have numerous interaction partners, NFS1 is mainly localized in mitochondria with a crucial role in the biosynthesis of Fe-S clusters. Additionally, NFS1 is also located in smaller amounts in the cytosol with a role in Moco biosynthesis and mcm5s2U34 thio modifications of nucleosides in tRNA. NFS1 and IscS were conclusively shown to have different interaction partners in their respective organisms. Here, we used functional complementation studies of an E. coli iscS deletion strain with human NFS1 to dissect their conserved roles in the transfer of sulfur to a specific target protein. Our results show that human NFS1 and E. coli IscS share conserved binding sites for proteins involved in Fe-S cluster assembly like IscU, but not with proteins for tRNA thio modifications or Moco biosynthesis. In addition, we show that human NFS1 was almost fully able to complement the role of IscS in Moco biosynthesis when its specific interaction partner protein MOCS3 from humans was also present.

Photoinduced Charge Shifts and Electron Transfer in Viologen-Tetraphenylborate Complexes: Push-Pull Character of the Exciplex

Viologen-tetraarylborate ion-pair complexes were prepared and investigated by steady-state and time-resolved spectroscopic techniques such as fluorescence and femtosecond transient absorption. The results highlight a charge transfer transition that leads to changes in the viologen structure in the excited singlet state. Femtosecond transient absorption reveals the formation of excited-state absorption and stimulated emission bands assigned to the planar (kobs < 1012 s-1) and twisted (kobs 1010 s-1) structures between two pyridinium groups in the viologen ion. An efficient photoinduced electron transfer from the tetraphenylborate anionic moiety to the viologen dication was observed less than 1 mus after excitation. This is a consequence of the push-pull character of the electron donor twisted viologen structure, which helps formation of the borate triplet state. The borate triplet state is deactivated further via a second electron transfer process, generating viologen cation radical (V+). Interested yet?

Heterometallic iodoplumbates modified by copper(I) or silver(I) with viologens

Cu/Ag(I) were introduced into iodoplumbate systems to produce two new heterometallic iodoplumbates with viologen as templates, i.e. (PV)2(Pb2Cu2I10) (1) and [(BV)(Pb2AgI7)]n (2) (PV2+?=?propyl viologen, BV2+?=?benzyl viologen), in which the common connection of PbI6 units have been remarkably altered. In (PV)2(Pb2Cu2I10) (1), two PbI6 octahedra are bridged by two CuI4 tetrahedra via face-sharing to give a (Pb2Cu2I10)4? cluster, but the ternary one-dimensional polymeric (Pb2AgI7)n 2n? of [(BV)(Pb2AgI7)]n (2) is assembled from edge-sharing AgI4 tetrahedra and PbI6 octahedra. Their optical band gaps and fluorescence were also discussed. The absorption edges of haloplumbates could be engineered by introduction of suitable conjugated molecules as templates.

Anaerobic degradation of the plant sugar sulfoquinovose concomitant with H2S production: Escherichia coli k-12 and desulfovibrio sp. Strain DF1 as co-culture model

Sulfoquinovose (SQ, 6-deoxy-6-sulfoglucose) is produced by plants and other phototrophs and its biodegradation is a relevant component of the biogeochemical carbon and sulfur cycles. SQ is known to be degraded by aerobic bacterial consortia in two tiers via C3-organosulfonates as transient intermediates to CO2, water and sulfate. In this study, we present a first laboratory model for anaerobic degradation of SQ by bacterial consortia in two tiers to acetate and hydrogen sulfide (H2S). For the first tier, SQ-degrading Escherichia coli K-12 was used. It catalyzes the fermentation of SQ to 2,3-dihydroxypropane-1-sulfonate (DHPS), succinate, acetate and formate, thus, a novel type of mixed-acid fermentation. It employs the characterized SQ Embden-Meyerhof-Parnas pathway, as confirmed by mutational and proteomic analyses. For the second tier, a DHPS-degrading Desulfovibrio sp. isolate from anaerobic sewage sludge was used, strain DF1. It catalyzes another novel fermentation, of the DHPS to acetate and H2S. Its DHPS desulfonation pathway was identified by differential proteomics and demonstrated by heterologously produced enzymes: DHPS is oxidized via 3-sulfolactaldehyde to 3-sulfolactate (SL) by two NAD+-dependent dehydrogenases (DhpA, SlaB); the SL is cleaved by an SL sulfite-lyase known from aerobic bacteria (SuyAB) to pyruvate and sulfite. The pyruvate is oxidized to acetate, while the sulfite is used as electron acceptor in respiration and reduced to H2S. In conclusion, anaerobic sulfidogenic SQ degradation was demonstrated as a novel link in the biogeochemical sulfur cycle. SQ is also a constituent of the green-vegetable diet of herbivores and omnivores and H2S production in the intestinal microbiome has many recognized and potential contributions to human health and disease. Hence, it is important to examine bacterial SQ degradation also in the human intestinal microbiome, in relation to H2S production, dietary conditions and human health.

Fabrication of a MoS2/Graphene Nanoribbon Heterojunction Network for Improved Thermoelectric Properties

A number of 2D materials have been developed that have properties different from bulk materials due to the quantum confinement effect. These 2D materials can also form a vertical van der Waals heterojunction at a large interface with other 2D materials, resulting in unique electronic and thermoelectric properties. However, it is difficult to fabricate a van der Waals heterostructure of 2D materials that can provide a sufficient temperature gradient while also forming carrier paths across the vertical heterojunction. Here, a heterojunction network structure constructed of highly conductive sub-20-nm graphene nanoribbons (GNRs) arrays stacked on a semiconducting molybdenum disulfide (MoS2) monolayer is suggested to maximize the heterojunction effect on carrier transport. This heterojunction network allows the carriers inevitably pass back and forth between the GNR and the MoS2 through the vertical heterojunction, effectively utilizing the interfacial properties in thermoelectricity. This structure also can modify the band structure by controlling the linewidth of the nanoribbons, or introduce an interlayer at the heterojunctions to enhance the tunneling effect between the two layers, thus significantly improved thermoelectric properties are achieved such as enhanced electrical conductivity of 700 S m?1 and a high power factor of 222 muW m?1 K?1.
