Selective oxidation of 5-hydroxymethylfurfural to 2,5-diformylfuran with ZnInS 2D nanosheets and atmospheric O under visible light

Two dimensional (2D) ZnIn 2 S 4 nanosheets were synthesized via a trisodium citrate-assisted hydrothermal method and used for the oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-diformylfuran (DFF) and 5-formyl-2-furan (FFCA) with atmospheric O 2 under visible light irradiation. The conversion of...

Description
Summary:Two dimensional (2D) ZnIn 2 S 4 nanosheets were synthesized via a trisodium citrate-assisted hydrothermal method and used for the oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-diformylfuran (DFF) and 5-formyl-2-furan (FFCA) with atmospheric O 2 under visible light irradiation. The conversion of HMF reached 95%, and the DFF selectivity was 70% after 1.5 h of illumination. Photogenerated holes (h + ), &z.rad;O 2 − and carbon-centred radicals are the dominant reaction species. 2D ZnIn 2 S 4 nanosheets were synthesized via a trisodium citrate-assisted hydrothermal method and used for the oxidation of 5-hydroxymethylfurfural to 2,5-diformylfuran and 5-formyl-2-furan with atmospheric O 2 under visible light irradiation.
