碳氮掺杂的CoRuO催化剂用于酸性水氧化
CN-doped CoRuO electrocatalysts for efficient acidic oxygen evolution reaction
摘要
Abstract
The development of highly efficient and stable acidic oxygen evolution reaction(OER)catalysts is of paramount importance for proton exchange membrane water electrolysis technology.In this study,we employed a carbon-nitrogen(CN)co-doping strategy to optimize the electronic structure and surface properties of CoRuO-based catalysts,thereby significantly enhancing their OER activity and stability in acidic media(0.5 mol·L-1 H2 SO4).Experimental results demonstrate that CN doping not only enhances the intrinsic activity of the Co and Ru sites but also improves the catalyst's conductivity and dissolution resistance,resulting in an overpotential of 188 mV at a current density of 10 mA·cm-2 and stable operation for over 45 h.Comprehensive X-ray photoelectron spectroscopy(XPS)analysis and electrochemical characterization reveal that CN doping induces favorable charge redistribution among metal ions,which effectively accelerates the OER kinetics.This work elucidates the crucial role of CN doping in modulating catalytic performance and provides a novel design strategy for developing high-performance and durable acidic OER catalysts.关键词
