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

In this paper, a type II CdIn 2 S 4 /g-C 3 N 4 heterostructure was applied to the selective photo-oxidation of HMF to DFF. The electrons and holes can be separated through the electron transfer of the heterojunction to improve the catalytic efficiency.
