Synthesis of Hydrogen Peroxide (Anthraquinone Process)

H2 + O2 → H2O2

Overview

The industrial synthesis of hydrogen peroxide uses the anthraquinone auto-oxidation process, where hydrogen and oxygen combine with the aid of an anthraquinone carrier and palladium catalyst. The net reaction is the direct combination of hydrogen and oxygen to form hydrogen peroxide.
