▎ 摘　　要

NOVELTY - Preparing rose-shaped structured bismuth(III) oxide/bismuth vanadate/graphene oxide nanocomposite photocatalytic material by one-step solvothermal process comprises in situ preparing bismuth(III) oxide/bismuth vanadate heterojunction and compositing with graphene oxide to obtain final product. USE - The material is useful for photocatalytic degradation of organic pollutants, and photocatalytic oxygen production (claimed). ADVANTAGE - The method: has simple process; and solves the problems that the existing bismuth(III) oxide photocatalyst electron holes are difficult to separate and the photoresponse range is limited, which is beneficial to the preparation of clean photocatalytic materials and the sustainable development of resources. The material has wide light response range, narrow band gap width, strong catalytic ability and low cost.
