Abstract
Abstract Developing highly‐efficient and robust bifunctional electrocatalyst for overall water splitting (OWS) is desirable, but it confronts long‐term challenge in the local structural reconstruction of catalyst during the hydrogen and oxygen evolution reaction (HER and OER). As inspired by the stable acid–base buffer system in human life, here we construct an electron buffer system to well address the key issue of structural reconstruction, in which the charge‐buffered fullerene renders Ru‐based active species to be reversibly shuttled between Ru and RuO 2 during HER and OER. Consequently, the as‐prepared Ru‐RuO 2 /C 60‐ x catalyst exhibits overpotentials of merely 7 and 194 mV at 10 mA cm −2 for HER and OER…
