化學(xué)專業(yè)畢業(yè)論文 鈷基負(fù)載型催化劑的制備與應(yīng)用

[摘 要]本論文以六水合硝酸鈷為鈷源，選取易得的二氧化硅（SiO2）、三氧化二鋁（Al2O3）和5A分子篩為載體，用浸漬法和沉積沉淀法制備了一系列的鈷基負(fù)載型催化劑，并分別考察了其在太陽光照射下對(duì)甲基橙的光降解效果。并對(duì)比了制備方法和載體對(duì)負(fù)載效果的影響。結(jié)果表明，對(duì)于SiO2載體，沉積沉淀法更有利于負(fù)載型催化劑的制備。

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.
