Rapid production of 38 mM HO in an alcoholic suspension of a WO photocatalyst under visible light.

Specific approaches to HO production over a WO photocatalyst under visible light irradiation, , (1) no use of a cocatalyst, (2) reaction under an O atmosphere, (3) reaction in a high concentration of alcohol, and (4) reaction at 60 °C, were found to be effective for rapid production of 38 mM HO.
