Pd/ZIF-67/TiO2纳米管复合催化剂的制备方法
摘要：
本发明涉及Pd/ZIF‑67/TiO2纳米管复合催化剂的制备方法。该方法是以钛板作为基体通过阳极氧化得到TiO2纳米管，550℃退火得到锐钛矿型TiO2，将TiO2纳米管基体浸入Co(NO3)2·6H2O/甲醇溶液和2‑甲基咪唑/甲醇溶液的混合液中，得到ZIF‑67/TiO2纳米管基体，将ZIF‑67/TiO2纳米管基体浸入一定浓度的PdCl2水溶液中得到Pd/ZIF‑67/TiO2纳米管复合材料。该材料作具有优良的捕获电子和产生更多的空穴的能力，在紫外‑可见宽波范围内具有良好的催化性能，能够在处理污水方面得到更广阔的应用前景，并且该材料的微孔结构特征可以用来选择性的进行催化反应。
摘要（英）：

The invention relates to a preparation method of a Pd/ZIF-67/TiO2 nanotube composite catalyst. The method comprises the steps of: carrying out anodic oxidation on a titanium plate as a substrate to obtain TiO2 nanotubes, annealing at 550 DEG C to obtain anatase type TiO2, immersing the TiO2 nanotube substrate in a mixed solution of Co(NO3).6H2O/methanol solution and 2-methylimidazole/methanol solution to obtain a ZIF-67/TiO2 nanotube substrate, and immersing the ZIF-67/TiO2 nanotube substrate to a certain concentration of PdCl2 aqueous solution to obtain the Pd/ZIF-67/TiO2 nanotube composite material. The material has excellent capability of capturing electrons and generating more holes, has good catalysis performance in an ultraviolet-visible wide wave range, can obtain broad application prospects in the aspect of sewage treatment, and can be used for selectively carrying out catalytic reaction due to the microporous structure characteristic.
