摘要 基于高比表面的介孔TiO2晶须,利用羟基磷灰石(HAP)对有机质良好的吸附特性,采用浸泡包裹的方法在介孔TiO2晶须光催化剂表面包覆少量羟基磷灰石,制得对有机质有较好吸附性能的催化剂前躯体,利用光化学沉积法在包裹后的前躯体上担载Ag.结果表明:表面包覆HAP质量分数为0.5%、担载Ag质量分数为1.9%后的介孔TiO2晶须光催化性能得到提高的同时又保证了对有机质的吸附能力. The adsorption performance of mesoporous titania whisker could be improved by coating some hydroxyapatite(HAP) with an excellent property of adsorbing organic compounds.The Ag/HAP/TiO2 photocatalyst was obtained by loading Ag on the prepared HAP/TiO2.The result showed that after coating 0.5% HAP and loading 1.9% Ag,the photocatalytic property of Ag/HAP/TiO2 was improved.
