Photocatalysis has proved its potential in cleaving the Cβ-O linkages between natural aromatic units lignin biomass and converting abundant to valuable monomer products. However, slow reaction rate low selectivity for monomers still hinder future industrial implementation. To address these challenges photocatalytic bond fragmentation, a Zn/S rich phase zinc indium sulfide photocatalyst was developed promote hydrogenolysis of lignin. In this work, water is first time, used as hydrogen donor...
Alkali metals and alkaline earth have been used to promote the catalytic performance of metal oxides in transesterification glycerol dimethyl carbonate, however, promotional roles dopants influencing not fully investigated which hinder development low-cost high-efficiency catalysts carbonate. This paper, for first time, systematically studied influence ionic radius valence state dopants, surface concentration basicity on La2O3 Our results suggest that are determining factors, while basic...
Photocatalysis has the potential for lignin valorization to generate functionalized aromatic monomers, but its application been limited by slow conversion rate and low selectivity desirable products. In this work, we designed phase junction CdS with coexposed hexagonal (100) cubic (220) facets improve photogenerated charge carriers' transfer efficiency from facet hydrogen an enhanced of monomers.

Lignin depolymerisation via photocatalytic cleavage of the selective interunit linkage in lignin could be a sustainable approach to produce monomeric aromatic chemicals. However, insufficient investigation C–C bond fragmentation has obstructed rational design efficient system and further limit yields monomers from depolymerisation.

Benzyl alcohol (BA) is a major biomass derivative and can be further converted into deoxybenzoin (DOB) benzoin (BZ) as high-value products for industrial applications through photocatalytic C-C coupling reaction. The process contains two reaction steps, which are (1) the of BA to hydrobenzoin (HB) intermediates (2) either dehydration HB DOB or dehydrogenation BZ. We found that generation BZ mainly determined by activation C
The localized plasmon resonance (LSPR) is recognized as an effective way to convert incident light energy and significantly boost the catalytic reaction. However, a comprehensive understanding of plasmon-thermo coupling mechanism still lacking. To address this knowledge gap, we investigate reaction pathway plasmonic enhancement photo-thermo coupled reverse water gas shift (RWGS) reactions over Au/γ-Al2O3. results indicate that both formate carboxyl pathways contribute overall m-formate...
Photocatalytic conversion of lignin into aromatic monomers by cleaving interunit C–O bonds is a promising approach to reduce reliance on fossil fuel resource. However, industrial implementation hindered insufficient reaction efficiency and selectivity for target monomers. This study addresses these challenges applying adsorbent-mediated catalysis developing quaternary CdxZn1–xIn2S4 photocatalyst. catalyst utilizes radical species from photocatalytic water dissociation promote the cleavage...
