What is the reaction between H2O2 and MnO2? - Quor

Answered April 14, 2018. No reaction takes place between H2O2 and MnO2, but MnO2 is used in the preparation of Oxygen in laboratories. Hydrogen peroxide (H2O2) decomposes very slowly. But in presence of manganese dioxide (MnO2), the reaction speeds up.
