Proton exchange membrane (PEM) water electrolysis has emerged as a highly promising technology for sustainable hydrogen (H2) production, but its widespread application relies heavily on the development of high-performance and cost-effective evolution reaction (HER) oxygen (OER) electrocatalysts. Currently, noble-metal-based materials (such Pt Ir/Ru oxides) serve benchmark electrocatalysts HER OER in acidic environments, their high cost limited availability pose major challenges toward industrialization. Low-cost noble-metal-free metal oxides are an important class functional with rich compositions structures, offering flexible electronic crystal structures tunable physical chemical properties.
