Abstract

Designing electrocatalysts for seawater splitting remains challenging. A Ru–Co alloy supported by an N-doped carbon substrate catalyst has been designed using etching and a low-temperature treatment method. Studies show that the superior performance of this catalyst is related to the hollow-structured N-doped carbon frame and surface reconstruction of the Ru–Co alloy.
