Hydrogen peroxide (H2O2) can produce hydrogen gas (H2) when catalyzed by certain materials such as manganese dioxide (MnO2) or platinum (Pt). This can be useful in various applications such as fuel cells, rocket propellants, and chemical synthesis. H2O2 can also be used as a disinfectant, bleaching agent, and for water treatment.
