【摘要】分别对掺杂纳米TiO2和分子筛负载纳米TiO2的光催化性能进行了对比研究,并对负载纳米TiO2进行了SEM检测。通过正交实验设计对其降解甲基橙溶液作了进一步研究,找出其最佳处理条件为:催化剂用量7.5g/L;光照时间1.5h;pH=3。更多还原

【Abstract】 Study on comparison between the photocatalytic property of doped nanometersized TiO2 and that of TiO2 thin film using molecular sieve as the carrier were reported respectively. A further research was done for the treatment of methyl orange through orthodox experiments and the optimal process conditions,which included 7.5 g/L catalyst weight per liter solution,1.5 h photocatalysis time and pH at 3 were found.更多还原
