TiO2负载Co2+、Cu2+催化剂的制备及其对甲酚催化氧化性能

用浸渍法制备了一系列以TiO2为载体的负载型催化剂，利用XRD和IR分析测试技术研究了负载Co2+与Cu2+后催化剂的表面结构，催化剂用于对甲酚氧化制备对羟基苯甲醛的反应中。 结果表明，n(Co2+)∶n(Cu2+)=1∶0.5时，催化剂的催化效果最佳。 在反应优化条件下，对甲酚的转化率可达100%，对羟基苯甲醛的选择性达95.2%。

Preparation and Catalytic Performance for p-Cresol Oxidation of Co~(2+) and Cu~(2+) Loaded TiO_2 Catalysts

A series of supported catalysts was prepared by wetness impregnation method with TiO_2 as substrate. The surface structures of the catalysts were characterized by XRD and IR. The catalysts prepared were used in the oxidation of p-cresol to p-hydroxybenzaldehyde. The results show that when the molar ratio of cobalt ions and copper ions was 1: 0.5, the catalyst had the best catalytic effect. Under optimized reaction conditions, the conversion of p-cresol was nearly 100%, the selectivity of p-hydroxybenzaldehyde was 95.2%.
