摘要
采用沉淀——离子交换法合成了BiOBr/I复合材料,通过降解有机物染料罗丹明B考察了其光催化性能.研究表明:BiOBrI-1复合材料是由BiOBr纳米片直接插入BiOI纳米微球所得,其具有更强的光催化性能的原因在于复合材料独特的微观形貌特性以及有效复合后的连续共溶体具有的合适能带值和BiOBr含量比率.
BiOBr/I Nanocomposites were synthesized through a precipitation-ion exchange.Its photocatalytic activities were investigated by the degradation of Rhodamine-B（RhB）under visible light irradiation.The prepared samples were characterized by XRD,FESEM,EDS and XPS,etc.The results show that BiOBrI-1complex is made when BiOBr nanosheets plug directly BiOI microspheres.Its higher photocatalytic activities are due to the unique microstructure morphology and to the appropriate band value and proportion of BiOBr in the continuous co-dissolved solution after the effective composite.
