Hydrogen peroxide decomposition in wet heterogeneous catalytic oxidation

Decomposition of hydrogen peroxide is a key step in catalytic peroxide oxidation process.Hydrogen peroxide decomposition kinetics was studied over CuO/γ-Al2O3 catalyst.The effects of several operating parameters such as H2O2 dosage,catalyst loadings,pH value,and the temperature on the hydrogen peroxide decomposition were discussed.The results showed that these factors played a significant role on the decomposition of hydrogen peroxide.Therefore,these factors should be controlled in the practical use so that optimum results would be obtained.
