Direct synthesis of hydrogen peroxide from hydrogen and oxygen over palladium catalyst supported on H3PW12O40-incorporated MCF silica

▶ Direct synthesis of hydrogen peroxide from hydrogen and oxygen was conducted. ▶ Palladium catalyst supported on H3PW12O40-incorporated MCF silica was used. ▶ Acidity of Pd/H3PW12O40-MCF catalyst played an important role. ▶ Yield for hydrogen peroxide increased with increasing acidity of the catalyst.
