摘要
以分析MB初始浓度,催化剂用量以及pH值对光催化速率的影响为基础,研究了氮掺杂二氧化钛催化亚甲基蓝动力学行为;结果表明催化反应符合Langmuir等温吸附规律,pH值为3时降解速率达到最大值,并且光催化速率的变化随着催化剂用量呈现饱和现象。
Kinetics of N-doped TiO2 photocatalyst catalyzing Methylene Blue was researched by analysis of the influence of the MB initial density, the catalyst amount and the pH value on photochemical catalysis speed. The result show that the photocatalytic process conforms to the rule of Langmuir adsorption isotherm, catalysis speed is the quickest when the pH value is 3 and the catalysis speed change presents the saturated phenomenon following the catalyst amount.
