载体对二氧化钛光催化降解苯的影响

Effects of Adsorbents Used as Supports for Titanium Dioxide Loading on Photocatalytic Degradation of Benzene

摘要:

研究了以活性炭、沸石、膨润土和硅藻土为负载的TiO2对空气中苯的光催化降解性能，并与无负载的TiO2进行了比较，结果表明，选择合适的载体可以起到吸附与催化氧化的协同作用，提高催化效率。

Abstract:

TiO2-loaded adsorbents, such as activated carbon, zeolite, bentonite, and diatomite, were prepared. And the photocatalytic degradation of benzene in gas phase was studied then. The efficiency of photocatalysis was compared with that of naked TiO2. The experiment results indicated that the suitable adsorbent supports make a high concentration environment of organic substances of target around the loaded TiO2 by adsorption, and the rate of photooxidation is enhanced as a consequence.
