Water splitting into hydrogen and oxygen in order to store light or electric energy requires efficient electrocatalysts for practical application. Cost-effectiveness, abundance, efficiency are the major challenges of electrocatalysts. Herein, this paper reports use low-cost 304-type stainless steel mesh as suitable water. The commercial self-support is subjected exfoliation heteroatom doping processes. modified electrocatalyst displays higher evolution reaction property than IrO2 , comparable with that Pt. More importantly, an all-stainless-steel-based alkaline electrolyzer (denoted NESSP//NESS) designed first time, which possesses outstanding stability along lower overall voltage conventional Pt//IrO2 at increasing current densities. remarkable electrocatalytic properties electrode can be attributed unique exfoliated-surface morphology, doping, synergistic effect from uniform distribution interconnected elemental compositions. This work creates prospects utilization low-cost, highly active, ultradurable electrochemical conversion.
