“…67–75 Hence, rational design over electrocatalysts with low overpotential and outstanding electrochemical stability is highly demanded. 76–81 As well known, Pt and Pt-based electrocatalysts are by far the predominant materials for electrocatalytic HER. 82–84 However, they also face some challenges when used for industrial applications, including high cost, limited supply, and poor electrochemical stability in harsh environments.…”
