Fast decomposition of hydrogen peroxide by Zeolitic imidazolate framework-67 crystals

Abstract The decomposition of hydrogen peroxide was determined in the neutral solution of ZIF-67 crystals. The fast decomposition of H 2 O 2 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.
