Photocatalytic selective oxidation of biomass-derived 5-hydroxymethylfurfural to 2,5-diformylfuran under ambient conditions over CdIn₂S₄/g-C₃N₄ heterojunctions

Abstract

Selective photocatalytic oxidation rather than mineralisation is essential for the catalytic valorisation of biomass, which requires precise control of the generation of reactive oxygen species via the rational construction of...

Binder-Free Carbon Nitride Panels for Continuous-Flow Photocatalysis

“…It should be noted that using CN panels in continuous-flow conditions, we achieved high HMF conversion rate (1185 μmol h –1 g –1 ), which is among the state-of-the-art heterogeneous photocatalysts (Figure c and Table S5). − Postoperational characterization studies emphasize the structural and chemical stability of the panel after a continuous operation for 24 h (Figures S28 and S29). This stability and the high HMF conversion in pure water motivate the adaptation of continuous-flow photochemistry to oxidation reactions of more challenging biomass substrates (e.g., lignin, cellulose, and glycerol).…”

Bridging and terminal hydroxyl groups of Zr(OH)4 as active sites for the ultraselective transformation of biomass-based alcohols

“…13–15 From the perspective of green and sustainable chemistry, upgrading biomass-based compounds by oxidative dehydrogenation or dehydration are critically important methods, which may make it possible to partly replace crude oil feedstocks with biomass. 16–18 Moreover, the oxidative dehydrogenation of alcohols to corresponding carbonyl compounds and dehydration of alcohols to corresponding alkene compounds play important roles in academic organic chemistry research and industrial application. 19–21 As a typical biomass-based alcohol monomeric molecule, 1-phenylethanol can be transformed into a variety of organic intermediates, such as acetophenone and styrene.…”
