| 摘 要： | 采用涂覆法制备了CoAl2O4/蜂窝陶瓷催化剂。利用X射线衍射、N2吸附-脱附和透射电镜等方法对所制备的催化剂进行了表征，并分析了其催化臭氧化降解对苯二酚的效能。结果表明，CoAl2O4/蜂窝陶瓷的晶相属于典型的尖晶石结构，具有较大的比表面积、孔容和孔径，分别达到77 m2·g-1、0.001 7 cm3·g-1和3.9 nm。CoAl2O4/蜂窝陶瓷催化臭氧化对苯二酚的去除率高达81.2%，COD去除率可达47.7%。在叔丁醇存在的条件下，对苯二酚的去除率显著下降，说明CoAl2O4/蜂窝陶瓷催化臭氧化遵循羟基自由基机理。

| Abstract: | CoAl2O4/ceramic honeycomb catalyst was prepared by coated method and was characterized by X-ray diffraction, N2 adsorption-desorption and transmission electron microscope. Catalytic ozonation of hydroquinone was conducted to evaluate its catalytic activity. The results showed that the crystal phase of CoAl2O4/ceramic honeycomb belonged to a typical spinel structure with a large specific surface area of 77 m2·g-1, pore volume of 0.001 7 cm3·g-1 and pore size of 3.9 nm. The removal efficiencies of hydroquinone and COD during ozonation of O3-CoAl2O4/ceramic honeycomb were 81.2% and 47.7%, respectively. The degradation efficiency of hydroquinone decreased significantly after the addition of tert-butanol, and the ozonation of CoAl2O4/ceramic honeycomb catalyst should follow a hydroxyl radical mechanism. |
