High-performance water oxidation catalysts based on the spontaneous deposition of ruthenium on electrochemically exfoliated graphene oxide†
Abstract
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 VRHE), WOR onset overpotentials of 0.2 V or less, and stable long term performances (1 mA cm−2).
