| 摘 要： | 以工业TiOSO4溶液水解得到的多孔偏钛酸为载体,通过光催化还原法制备了多孔Ag/TiO2光催化剂.用XRD、SEM、EDS及低温氮吸附脱附法对样品进行了表征.以光催化氧化降解亚甲基蓝为目标反应,考察了不同制备条件对样品光催化活性的影响.结果表明,制备的Ag/TiO2为负载有非晶态纳米银粒的锐钛矿型TiO2光催化剂,比表面积高达197m2/g,其光催化活性远优于未载银的TiO2.

| Abstract: | Porous metatitanic acid isolated from hydrolysis reaction of industrial TiOSO4 solution as carrier,porous Ag/TiO2 photocatalyst was prepared via photocatalytic reduction reaction process.The prepared Ag/TiO2 was characterized by means of XRD,SEM,EDS and N2 adsorption-desorption isotherm.The effects of preparing conditions on photocatalytic activity of the Ag/TiO2 were examined through the photocatalytic degradation reaction of methylene blue.The result shows that Ag/TiO2 is anatase TiO2 loaded amorphous nano-particle silver,with a specific surface area of 197m^2/g.The photocatalytic performance of Ag/TiO2 is better than alone TiO2. |
