摘要
用溶胶 -凝胶法制备了纳米二氧化钛 ,使用XRD和SEM确定产物的晶相和形貌 ,用激光粒度仪分析产物的表观粒径和粒径分布 .考察了光催化剂二氧化钛的量、溶液的初始浓度、pH值和H2 O2 的量等因素对光催化降解甲基蓝的影响 .
Nanocrystaline TiO 2 was prepared with the sol-gel method.Its crystalline phase and particle size were determined by XRD and SEM .The granularity and its distributing for the products were analyzed by laser granularity. In our research, the effects of some factors such as the amount of TiO 2 used, the initial concentration and pH value of the solution containing Methyl blueness ,and the amount of H 2O 2 used on TiO 2 photocatalysis for degrading methyl blueness were investigated.
