在ZIF-67晶体的中性溶液中测定过氧化氢的分解。H2 O2的快速分解可以在反应物混合后几秒钟内用肉眼观察到。在分解反应后，观察到ZIF-67晶体的褶皱表面。分解反应符合一级动力学。温度依赖性研究计算出活化能为37 kJ mol（-1）。基于所得结果，提出了一种可能的机制。(C)2018爱思唯尔B. V.保留所有权利。
The decomposition of hydrogen peroxide was determined in the neutral solution of ZIF-67 crystals. The fast decomposition of H2O2 can be observed by naked eyes in seconds after mixing the reactants. A crumpled surface was observed for ZIF-67 crystals after the decomposition reaction. The decomposition reaction was found to follow the first-order kinetics. Temperature-dependent studies calculated that the activation energy was 37 kJ mol(-1). Based on the obtained results, a possible mechanism was proposed. (C) 2018 Elsevier B.V. All rights reserved.
