Abstract

Abstract : Construction of ternary RuP2 /Ti4 P6 O23 @TiO2 photocatalysts for efficient photocatalytic biomass selective oxidation and water splitting. Abstract : High-efficiency visible-light-driven biomass conversion, coupled with water splitting, has attracted considerable attention, but the achievements have been rather limited. Herein, the ternary RuP2 /Ti4 P6 O23 @TiO2 -7 photocatalyst was successfully constructed for efficient photocatalytic hydrogen evolution and high selectivity biomass conversion simultaneously. A series of nanospheres were uniformly arranged on the surface of RuP2 /Ti4 P6 O23 @TiO2 -7, and it exhibited a fast photo-generated carrier rate and wide visible light absorption range due to the in situ incorporated RuP2 and Ti4 P6 O23 to form the heterojunction. The hydrogen evolution achieved 16.3 mmol g −1 h −1 accompanied by lactic acid production that reached 2.41 mmol g −1 h −1 . Moreover, the RuP2 /Ti4 P6 O23 @TiO2 -7 photocatalytic system is suitable for different biomass-derived monosaccharides and macromolecule xylan, in which the pentoses are more active than hexoses. For xylan, lactic acid production reached 0.63 g gxylan −1 . Notably, this work shows an efficient utilization of water splitting and biomass conversion via RuP2 /Ti4 P6 O23 @TiO2 -7 photocatalysis and provides new insight into biomass reforming and water splitting.
