Visible-light-driven coproduction of diesel precursors and hydrogen from lignocellulose-derived methylfurans

Visible-light-driven amino acids production from biomass-based feedstocks over ultrathin CdS nanosheets

“…Indeed, photocatalysis has recently shown encouraging potentials in the valorization of biomass feedstocks 45 . Wang and co-workers 46 reported the photocatalytic coproduction of diesel precursors and hydrogen from biomass-derived furans using Ru-doped ZnIn 2 S 4 catalysts, alkane formation from fatty acid over Pt/TiO 2 photocatalysts 47 , as well as the production of methanol and syngas from bio-polyols and sugars 48 . Reisner and co-workers 49 studied the photocatalytic conversion of lignocellulose into H 2 over cadmium sulfide quantum dots.…”

Beyond Artificial Photosynthesis: Prospects on Photobiorefinery

“…Under visible‐light irradiation, the best catalyst (Zn 0.5 Cd 0.5 S−P) can generate the impressive H 2 production rate of 419 μmol h −1 g −1 , and the H 2 production was further promoted to 786 μmol h −1 g −1 when HMF was introduced into the catalytic system, meanwhile the value‐added product, DFF, was simultaneously achieved. Very recently, Wang's group successfully coupled the synthesis of diesel fuel precursors (DFPs) from lignocellulose‐derived methylfurans with H 2 production using Ru‐doped ZnIn 2 S 4 photocatalyst Figure . DFPs can be converted to biodiesel after hydrodeoxygenation.…”

Visible-light-driven organic transformations integrated with H2 production on semiconductors

“…Recently, Wang et al reported a Ru-doped ZnIn 2 S 4 photocatalyst, which was prepared following a one-pot hydrothermal method, in order to achieve the dehydrogenative C-C coupling of lignocellulose-derived methylfurans to diesel fuel precursors and H 2 under visible light irradiation. 34 Benefiting from the Ru dopants to improve the light harvesting and charge separation efficiency, this Ru-ZnIn 2 S 4 photocatalyst showed decent performance with a diesel fuel precursor production rate of 1.04 g g catalyst À1 h À1 and high selectivity (496%), as well as a H 2 production rate of 6.0 mmol g catalyst À1 h À1 . Subsequent hydrodeoxygenation treatment of the obtained coupling products of furanics would result in the desired diesel fuels containing straight-and branched-chain alkanes.…”

“…In addition to the unimolecular oxidation reactions for the consumption of photo-generated holes, bimolecular oxidative coupling reactions can also be achieved on semiconductors under visible light irradiation with simultaneous H 2 production (Scheme 4). [32][33][34][35] For instance, Xie and co-workers reported a CdS nanorod photocatalyst decorated with MoS 2 nanofoams for the direct conversion of methanol to ethylene glycol (EG) with 90% selectivity and high efficiency together with H 2 production upon visible light irradiation. 33 CdS enables the facile generation of CH 2 OH for subsequent C-C coupling and the MoS 2 nanofoam co-catalyst improves the evolution of H 2 and the overall photocatalytic activity.…”
