▎ 摘 要
Novel water oxidation reaction (WOR) catalysts prepared via spontaneously depositing Ru on electrochemical graphene oxide (EGO), Ru(III)@EGO and Ru(VII)@EGO, produced outstanding specific activities over 100 A g(-1) (@ 1.8 V-RHE), WOR onset overpotentials of 0.2 V or less, and stable long term performances (1 mA cm(-2)).
