NOVELTY - Preparing reduced graphene oxide supported ruthenium selenide bifunctional electrocatalyst comprises (1) dispersing monolayer graphene oxide into deionized water, ultrasound to obtain a graphene oxide dispersion; (2) placing ruthenium source and the selenium source in the graphene oxide dispersion in step (1) and stir vigorously, introducing a reducing agent and ultrasonically disperse; (3) the dispersion, placing solution in a polytetrafluoroethylene liner, placed in a stainless steel autoclave, and heating in a blast drying oven at 120 °C, centrifugally washing resulting product with deionized water and ethanol, and placed in a vacuum drying oven (4) RuSe2/r-GO precursor was calcined under the protection of nitrogen, and the calcined product was washed and vacuum-dried. USE - Preparation method of reducing graphene oxide loaded with ruthenium diselenide bi-functional electrocatalyst used for hydrogen evolution application. ADVANTAGE - The catalyst has excellent catalytic activity and good stability to the electro-catalysis hydrogen evolution and oxygen evolution reaction. The method is simple and easy to operate, fast and efficient, and provides high yield of the catalyst. The catalyst is protected from electrochemical corrosion. The crystalline and electronic effects of catalyst are greatly improved by thermal annealing and calcining.
