以葡萄糖为模板和碳源,经水热反应和高温煅烧得到碳掺杂介孔TiO2中空微球(C-TiO2),并以C-TiO2为载体,将AgNO3和NaH2PO4负载到TiO2介孔孔道中,在光催化过程中原位生成Ag3 PO4提高TiO2的光催化活性.利用XRD、SEM、TEM以及UV-Vis DRS对样品进行表征.以罗丹明B为模拟污染物,对样品在紫外光和可见光下的催化性能进行表征.结果表明,Ag(Ⅰ)敏化后TiO2的载银量为5.6％时光催化活性最佳,在紫外光下20 min时降解率为98.6％,可见光下40 min降解率为99.3％.“,”Carbon-doped mesoporous TiO2 hollow microspheres (C-TiO2) are prepared by hydrothermal reaction method and calcination method using glucose as template and carbon source.Using the prepared C-TiO2 as supporter,AgNO3 and NaH2PO4 are supported into the mesoporous channels of TiO2 and form Ag3PO4 in-situ during the photocatalytic process,which can improve the photocatalytic activity of TiO2.The Ag (Ⅰ) sensitized C-TiO2 samples are characterized by XRD,SEM,TEM,and UV-Vis DRS.The photocatalytic activity of the sensitized samples are evaluated through photocatalytic degradation of simulated contaminant Rhodamine B under ultraviolet light and visible light,respectively.The photocatalytic activity is the best when the content of Ag in Ag (Ⅰ) sensitized C-TiO2 is 5.6％,over which the degradation rate is 98.6％ under the irradiation of ultraviolet light for 20 min and is 99.3％ under the irradiation of visible light for 40 min.
