ABSTRACT
In2O3/In2S3 heterostructures were successfully constructed using alginate-derived In2O3 hollow fibers as precursor, following In2S3 loaded onto the In2O3 hollow fibers. Compact interface between the (222) plane of In2O3 and (220) plane of In2S3 is fabricated, which accelerates the charge transfer and separation, effectively enhancing the photocatalytic HER performance (rates up to 111.2 μmol/g/h) in conduction band and conversion of HMF in valence band. -
