摘要
采用共沉淀法中的变化pH值法和过饱和恒定pH值法制备了含铜三元类水滑石化合物CuMAl-HTLcs、通过XRD和IR表征其结构。并将此类水滑石应用于苯甲醛H2O2的氧化中,结果表明CuZnAl-HTLcs、CuNiAl-HTLcs两种类水滑石对苯甲醛H2O2氧化的催化活性远高于其它金属离子搭配的CuMAl-HTLcs,经老化的与未经老化的CuMAl-HTLcs对苯甲醛H2O2氧化的的催化活性相比,前者弱于后者。
CuMAl-hydrotalcite-like compounds were synthesized by the methods of variable pH value of coprecipita tion and invariable pH value of supersaturation. The product structures were characterized by XRD and FTIR. The catalytic action of CuMAl-HTLcs were investigated bY the oxidation of benzaldehyde to benzoic acid using HeO2 as oxidant. The result showed that CuZnAl-HTLcs and CuNiAl-HTLcs had much higher activity than other metal collocated CuMAl-HTLcs,and aged CuMAl-HTLcs had lower activity than non-aged ones.
