摘要
以四氯化钛为钛源,AlCl3为粘结剂,煤粉为致孔剂,采用溶胶凝胶法制备了二氧化钛(TiO2)/膨润土复合光催化剂;对该催化剂的吸附及光催化降解特性作了探讨。结果表明:该催化剂孔隙发达,并具有良好的吸附特性及紫外光降解特性,吸附行为符合Langmuir二级吸附速率方程。
Titanium tetrachloride, AlCl3 and pulverized coal were used as a titanium source, a bind- er and a porogenic agent respectively, the TiO2/ Bentonite Composite Catalysis was prepared by Sol-Gel method. The Characteristic of Adsorption and Photocatalytic Degradation about the catalysis were explored. The experimental results showed that this catalysis exhibited with well developed poros- ity, and presented both better absorption and Photocatalytic degradation characteristics. The absorption behavior of this catalysis follows Langmuir Second-Order Rate Equation for absorption.
