一种Ag/AgBr/Ga2O3异质结构光催化材料及其制备方法
摘要：
本发明属于光催化材料研发技术领域，具体涉及利用一种Ag/AgBr/Ga2O3异质结构光催化材料及其制备方法。一种Ag/AgBr/Ga2O3异质结构光催化材料，是由Ga2O3、AgNO3和NaBr制备而成，所述的Ga2O3、AgNO3和NaBr的摩尔比为n(Ga2O3)：n(AgNO3)：n(NaBr)＝1：2：2。本发明的Ag/AgBr/Ga2O3光催化材料显著改善了光生载流子的分离，大大提高了材料的光催化性能，在254nm的紫外光照射下，以Ag/AgBr/Ga2O3为光催化剂降解甲基橙，30min降解率达89％；而以Ag/AgBr和Ga2O3为催化剂，60min降解率分别为74％和48％；本发明的Ag/AgBr/Ga2O3光催化材料的制备方法在室温常压下即可完成实施，成本低、操作简便，易于工业化生产。
摘要（英）：

The invention belongs to the technical field of photocatalytic material development, and particularly relates to a Ag/AgBr/Ga2O3 heterostructure photocatalytic material and a preparing method thereof. The Ag/AgBr/Ga2O3 heterostructure photocatalytic material is prepared from Ga2O3, AgNO3 and NaBr, and the molar ratio of n(Ga2O3) to n(AgNO3) to n(NaBr) is 1:2:2. The Ag/AgBr/Ga2O3 heterostructure photocatalytic material remarkably improves separation of photon-generated carriers, photocatalytic performance of the material is greatly improved, under irradiation of 254-nm ultraviolet light, Ag/AgBr/Ga2O3 is used as a photocatalyst for degrading methyl orange, and the 30-min degradation rate reaches 89%; with Ag/AgBr/Ga2O3 as a catalyst, the 60-min degradation rates are 74% and 48% respectively. The preparing method of the Ag/AgBr/Ga2O3 photocatalytic material can be implemented under normal pressure at the room temperature and is low in cost and easy to operate, and industrial production is easy to achieve.
