在合成缺位取代的钼磷杂多化合物Na_5[PM(H_2O)Mo_(11)O_(39)]·5H_2O[M=Mn~(2+)、Co~(2+)、Ni~(2+)、Cu~(2+)、Zn~(2+)的基础上,研究了它们在H_2O_2分解反应中的催化活性规律.并与相应的硫酸盐MSO_4在同一反应中的催化活性规律作了比较,发现虽在活性上缺位的杂多化合物较之硫酸盐高,但对过渡金属而言,其活性顺序是一致的.在此基础上,以含铜缺位取代的杂多化合物和CuSO_4为例,对它们在H_2O_2分解反应中的催化动力学性质作了深入的研究,对反应机理作了讨论.
In the synthesis of vacancies substituted molybdophosphoric compounds Na_5 [PM (H_2O) Mo_ (11) O_ (39)] 5H_2O [M = Mn 2+, Co 2+, ), Cu ~ (2 +) and Zn ~ (2+), and their catalytic activities in the decomposition of H_2O_2 were studied, and their catalytic activities were compared with those of the corresponding sulfate MSO_4 in the same reaction The results showed that although the active heteropoly compounds were absent, the activity order was the same for the transition metals, on the basis of which the heteropoly compounds substituted with Cu and CuSO 4 were For example, their catalytic kinetic properties in the decomposition of H_2O_2 have been studied in depth, and the reaction mechanism has been discussed.
