Herein a well‐sealed and thermostated kinetics assembly is designed and built, which can run stirred at different reaction temperatures. With the reaction assembly above and the volumetric method together, the hydrogen peroxide (H₂O₂) decomposition reaction kinetics is systematically investigated under a variety of reaction conditions over a copper‐doped buserite‐type layer manganese oxide (referred to as Cu‐buserite) as a heterogeneous catalyst. The overall second‐order rate law is fitted out by the linear regression analysis, with the reaction orders with respect to both H₂O₂ and Cu‐buserite determined to each be equal to 1, and then explicitly explained by the proposed Michaelis‐Menten like mechanism. The apparent activation energy E_a is estimated as 33.5 ± 2.5 kJ mol⁻¹.

铜-堇青石在良好密封和恒温动力学组件上催化的过氧化氢分解动力学

本文设计并制造了一个密封良好的恒温动力学组件，该组件可以在不同的反应温度下进行搅拌。通过以上反应组合和体积方法，系统地研究了在铜掺杂的镁铝矿型层氧化锰（简称铜镁铁矿）上各种反应条件下过氧化氢（H ₂ O ₂）的分解反应动力学。 ）作为非均相催化剂。通过线性回归分析拟合了总体二阶速率定律，其中关于H ₂ O ₂的反应阶数和铜-堇青石确定各自等于1，然后由拟议的米氏-米森特机制明确解释。表观活化能E _a估计为33.5±2.5 kJ mol ^-1。
