Spatial charge separation on the (110)/(102) facets of cocatalyst-free ZnIn2S4for the selective conversion of 5-hydroxymethylfurfural to 2,5-diformylfuran

ZnIn 2 S 4 has been screened as the best photocatalyst for selective HMF conversion (91.1%) into DFF (99.4% selectivity). The active site retrieval has been found to be an efficent approach to extend the photocatalyst durability.
