Abstract

ABSTRACT The development of efficient and durable bifunctional electrocatalysts is essential to simplify electrode design and fabrication in anion exchange membrane water electrolyzers (AEMWEs). However, most existing bifunctional catalysts suffer from poor stability and struggle to achieve high activity for both the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) simultaneously. Herein, we report Ir@Mn–Ni‐PA, phytic acid‐modified Mn‐doped Ni layered double hydroxide catalyst that incorporates atomically dispersed Ir sites through tailored design of single atoms. Synthesized via a simple hydrothermal method, the catalyst features hierarchical nanoarrays that enhance electron transport,…
