Abstract Both the introduction of photo-responsive metal oxide and the heteroatoms-doping into Pt-based catalysts may be a promising strategy to enhance its catalytic properties. In this paper, one-pot solid phase synthesis was employed to synthesize Pt (P)–V2O5/GNs catalyst, and it is shown that the addition of photo-responsive V2O5 and the doping of P are successfully achieved. Electrochemical measurements show that the Pt (P)–V2O5/GNs exhibits attractive bi-functional electrocatalytic property for ORR and HER, in comparison with the commercial PtRu/C-JM catalyst. More importantly, Pt (P)–V2O5/GNs presents much better electro-photo synergistic catalysis both for ORR and HER due to its excellent photo-responsive properties of V species in Pt (P)–V2O5/GNs, resulting in drastically enhanced catalytic activity and stability under the simulated sunlight irradiation.
