Abstract Oxygen evolution reaction is the essential anodic for water splitting. Designing tunable electronic structures to overcome its slow kinetics an effective strategy. Herein, molecular ammonium iron sulfate dodecahydrate employed as precursor synthesize C, N, S triatomic co‐doped Fe(Al)OOH on Ni foam (C,N,S‐Fe(Al)OOH‐NF) with asymmetric structure. Both in situ oxygen vacancies and their special configuration enable electron transfer between d‐p orbitals get increase of OER activity. Density functional theory calculation further indicates effect structure catalytic activity stability at vacancies. In alkaline solution, catalyst C,N,S‐Fe(Al)OOH‐NF shows good For OER, overpotential 10 mA cm −2 264 mV, tafel slope 46.4 mV dec −1 , HER 188 59.3 . The can maintain ≈100 h. This work has extraordinary implications understanding mechanistic relationship designing friendly metal (oxy)hydroxide catalysts.

Electrocatalytic water splitting, comprising the oxygen evolution reaction (OER) and hydrogen (HER), provides a sustainable route for production. While low-cost metal oxides (MOs) are appealing as alternatives to noble electrocatalysts, their application in acidic media remains challenging. However, dynamic nature of some MO surface structures under electrochemical conditions offers an opportunity rational catalyst design achieve bifunctionality OER HER. Here, we present closed-loop framework that integrates potential exploration (front-end), synthesis tests (mid-end), advanced characterizations (back-end). This combines crucial steps electrocatalyst exploration, including data mining, state analysis, microkinetic modeling, proof-of-concept experiments identify stable cost-effective catalysts splitting. Using this approach, RbSbWO6 is identified promising bifunctional first time, with experimental validation demonstrating its exceptional stability performance Notably, outperforms many other reported non-noble stoichiometric have not undergone major modifications These findings, derived from our Digital Catalysis Platform (DigCat), establish highly effective underscore power workflow accelerating discovery. begins DigCat platform, concludes validation, feeds into designing electrocatalysts systems such nitrides or carbides. study demonstrates importance high efficiency data-driven approaches new scientific discovery paradigm.
