Developing advanced catalysts for acidic oxygen evolution reaction (OER) is crucial sustainable hydrogen production. This study presents a multistage machine learning (ML) approach to streamline the discovery and optimization of complex multimetallic catalysts. Our method integrates data mining, active learning, domain adaptation throughout materials process. Unlike traditional trial-and-error methods, this systematically narrows exploration space using knowledge with minimized reliance on subjective intuition. Then, module efficiently refines element composition synthesis conditions through iterative experimental feedback. The process culminated in promising Ru-Mn-Ca-Pr oxide catalyst. workflow also enhances theoretical simulations strategy, providing deeper mechanistic insights aligned findings. By leveraging diverse sources multiple ML strategies, we demonstrate an efficient pathway electrocatalyst optimization. comprehensive, data-driven represents paradigm shift potentially benchmark electrocatalysts research.
