一步法合成金红石相TiO_2/沸石的光催化活性研究

Study on the Photocatalytic Activity of Rutile TiO_2/Zeolite by One-step Method

以天然沸石为基体,分析了活化天然沸石的晶相,并借助MS软件的Reflex模块对其进行精修,分析了活化沸石的成分和阳离子类型。合成了不同负载率的金红石相TiO2/沸石光催化剂,并对其晶相、比表面积、负载率和光催化活性进行了表征;利用上述光催化剂催化3种有机物的反应动力学参数表征了催化速率。

Using natural zeolite as matrix, the activation phase of the natural zeolite was analyzed. And using the module Reflex of MS software for crystal repair, the activated zeolite composition and cation type were analyzed. Load rate of different rutile TiOa/zeolite photocatalyst were synthesized, and their crystal phase, specific surface area, load rate and the photocatalytie activity were characterized. The use of the above-mentioned three types of optical catalyst kinetic parameters of organic matter eharacteried the catalytic rate of rutile TiO2/zeolite.
