摘要
采用溶胶-凝胶法,结合程序升温水热技术将制备的α-Fe_2O_3粉末加入磷钨酸(H_3PW_(12)O_(40))/TiO_2体系中,制备出α-Fe_2O_3/H_3PW_(12)O_(40)/TiO_2光催化剂,用WKL颗粒图像分析系统对催化剂颗粒进行分析,并用该催化剂光催化降解罗丹明B溶液。结果显示:α-Fe_2O_3/H_3PW_(12)O_(40)/TiO_2复合催化剂光催化降解罗丹明B的最佳条件为温度25℃、时间1h、光催化剂用量10mg、罗丹明B溶液50mL。在此条件下,罗丹明B的光催化降解率达到98.24%。
First of all,α-Fe2O3 powder was prepared by hydrothermal method,afterward by means of sol-gel method,and combined with temperature programmed hydrothermal technology.The preparedα-Fe2O3 powders were added to H3PW12O40/TiO2 system.α-Fe2O3/H3PW12O40/TiO2 photocatalyst powders were prepared.The particle surface was analyzed using WKL particle image analysis system,after,photocatalytic degradation of rhodamine B solution.The results demonstrated that the optimum conditions for photocatalytic degradation of rhodamine B by composite powders were 25℃,1 h,with the amount of photocatalyst was 10 mg.The reaction volume was 50 mL,and the degradation rate was 98.24%.
