TiO2负载Co2+、Cu2+催化剂的制备及其对甲酚催化氧化性能
摘要:
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 Co2+ and Cu2+ Loaded TiO2 Catalysts
Abstract:
A series of supported catalysts was prepared by wetness impregnation method with TiO2 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%.
