过氧化氢分解反应催化剂的研究

Research of the Catalysts of Hydrogen Peroxide Decomposition Reaction

以我校实验室中所有可能对过氧化氢分解反应有催化作用的18种试剂和5%过氧化氢溶液为原料,通过控制变量的方法进行对比实验,验证了二氧化锰等14种物质可作为过氧化氢分解反应的催化剂。基于反应条件和催化剂回收的难易程度方面考虑,二氧化锰应该是过氧化氢分解反应催化剂的最佳选择。在此研究基础上,从物质类别的角度归纳了各类催化剂对过氧化氢分解反应的催化机理。

The comparative experiments have been carried out by controlling variate method using 5%hydrogen peroxide solutions and 18 kinds of chemical reagents in the school laboratory as raw materials,which may have catalytic effect on the hydrogen peroxide decomposition reaction,to prove that the 17 kinds of chemical reagents,such as manganese dioxide,can be used as catalysts for hydrogen peroxide decomposition reactions Based on the reaction conditions and the difficulty of catalyst recovery,manganese dioxide should be the best choice for hydrogen peroxide decomposition reaction catalysts.On the basis of this research,the catalytic mechanism of various catalysts of the hydrogen peroxide decomposition reaction is summarized from the category of classification of substances.
