A superior cocatalytic behavior of reduced graphene oxide (rGO) was observed for the photocatalytic production of H2O2 in the TiO2-based system. The adsorption of phosphate on TiO2 enhanced the production of H2O2 up to a millimolar level. The in situ formation of cobalt phosphate on rGO/TiO2 enabled the photocatalytic production of H2O2 even in the absence of organic electron donors.
