化学专业毕业论文 钴基负载型催化剂的制备与应用

[摘 要]本论文以六水合硝酸钴为钴源，选取易得的二氧化硅（SiO2）、三氧化二铝（Al2O3）和5A分子筛为载体，用浸渍法和沉积沉淀法制备了一系列的钴基负载型催化剂，并分别考察了其在太阳光照射下对甲基橙的光降解效果。并对比了制备方法和载体对负载效果的影响。结果表明，对于SiO2载体，沉积沉淀法更有利于负载型催化剂的制备。

Abstract: Preparation of heterocatalyst loaded Co Abstract In this paper, a series of heterocatalyst were prepared from SiO2、 Al2O3 and 5A molecular sieves, and then was loaded transition metals, such as Co by dipping method and precipitating method. It was used in photocatalytic oxidation degradation of methyl orange under sunlight as light source. The effect of different preparation method and supporter were also discussed. The results indicated that the precipitating method was in favour of the preparation of heterocatalyst as for SiO2.
