Assembly of ultrathin PbBiO2Br nanosheets with enhanced visible light photocatalytic properties

Abstract

Novel assembly ultrathin PbBiO2Br nanosheets were synthesized by a facile solvothermal method. Structural characterizations indicate that the quaternary oxyhalide compound with a thickness of 8-9 nm can assemble into a hierarchical architecture. The e--h+ pairs can separate efficiently in such a 2D structure, so that ultrathin PbBiO2Br nanosheets exhibit superior photocatalytic activity towards the degradation of organic contaminants under visible light.
