A novel 2D nanosheets self-assembly camellia-like ordered mesoporous Bi12ZnO20 catalyst with excellent photocatalytic property

摘要: Abstract In this study, a kind of novel camellia-like Bi12ZnO20 photocatalyst was synthesized by self-assembly process 2D nanosheets, and the ordered mesoporous were distributed on surfaces camellia petals. A ZnO (OMZ) material must be used as precursor, sodium sulfosalicylate (Na3SSA) structure-directing agent in hydrothermal reaction process. The compound has even been reported Bi12ZnO20–Bi2WO6 heterostructures, it is only one literature that we can retrieve now, 3D catalyst never past. Bi based photocatalysts have much better photodegradation characteristics, but photolysis water characteristics unsatisfactory. prepared exhibited photocatalytic activity to Rhodamine B (RhB) degradation produce hydrogen under visible light irradiation which infrequent past references. structure could provide more adsorption capacity fluid active sites for reaction, enhance light-harvesting capacity, photogenerated electron-hole separation efficiency electronic transport efficient, all main reasons improvement properties. possible morphology growth mechanism discussed.
