首发时间:2016-06-24
摘要:用简单的一锅法合成三维分层结构的铅溴氧铋并对其进行XRD、SEM、紫外可见漫反射和氮气吸脱附等表征。将铅元素引入溴氧化铋不仅缩小了催化剂的带隙值增强了其对可见光的吸收,而且改善了光生电子与空穴对的分离效率。铅铋氧溴对光催化降解有机染料甲基橙、罗丹明B、亚甲基蓝、结晶紫表现出很好的活性。

One-pot Synthesis of lead bismuth oxybromide with Good Performance of Organic Dyes Photodegradation
Abstract:A series of three-dimensional hierarchical PbBiO2Br samples were synthesized using a one-pot method, and characterized by XRD, SEM, UV-vis DRS, and N2 adsorption-desorption techniques. The introduction of Pb to BiOBr results in not only narrowed band gap and enhanced visible light absorption, but also improved separation of photogenerated electrons and holes. PbBiO2Br show good performance for photocatalytic degradation of dyes (Methyl Orange, Rhodamine B, Methylene Blue, Crystal Violet ).
Keywords: Photocatalysis Lead bismuth oxybromide (PbBiO2Br) Organic dye Degradation
