【摘要】研究了第一系列可溶性后过渡金属盐对 H2 O2 分解反应的影响。结果表明 ,2 5℃时可溶性后过渡金属盐中 ,铜 ( )盐的催化活性最高 ;其催化活性与所含阴离子种类有关 ,不同可溶性铜( )盐的活性高低次序为 Cu( Ac) 2 ·H2 O>Cu SO4· 5 H2 O>Cu Cl2 · 2 H2 O>Cu( NO3 ) 2 · 3H2 O·3H2 O。文中对其催化机理进行了分析。更多还原

【Abstract】 The effect of hydrogen peroxide decomposition catalyzed by the soluble late transition metal salt,such as Fe（Ⅲ）,Co（Ⅱ）,Ni（Ⅱ）,Cu（Ⅱ） and Zn（Ⅱ） salt, were studied.The results showed that Cu（Ⅱ） salt had the highest catalytic activity for H₂O₂ decomposition in the soluble late transition metal salt,and its catalytic activity was related to it’s anionic kinds.The order of catalytic activity from high to low for soluble Cu（Ⅱ） salt is Cu（Ac）₂·H₂>CuSO₄·5H₂O>CuCl₂·2H₂O>Cu（NO₃）₂·3H₂O.In the same time,their catalytic mechanisms were discussed.更多还原
