Aiming at the issues of active species leaching and structural instability of Ru-based catalysts during the acidic oxygen evolution reaction (OER), this study adopts strategies including metal/non-metal doping, construction of solid solution structures, high-entropy alloys (HEAs), etc., to strengthen the metal-oxygen bonds in Ru-based catalysts, suppress the participation of lattice oxygen in the reaction, and develop a series of composite catalysts with high activity and stability. The data were collected from 2022 to 2025 at multiple locations, including Nankai University, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, and synchrotron radiation beamlines in Shanghai and Beijing. This dataset contains data generated during the preparation, characterization, and electrochemical testing of Pt-doped RuO₂, F-doped RuO₂, Zr- and W-doped RuO₂, RuTiOx solid solutions, SnRuOx solid solutions, and high-entropy oxides (HEOs). The data mainly cover scanning/transmission electron microscopy (SEM/TEM) images, high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) data, X-ray diffraction (XRD) patterns, X-ray photoelectron spectroscopy (XPS) data, X-ray absorption spectroscopy (XAS) data, infrared (IR) spectra, Raman spectra, differential electrochemical mass spectrometry (DEMS) data, three-electrode test data for acidic OER, and membrane electrode assembly test data for proton exchange membrane water electrolysis (PEMWE). All data were validated via multiple repeated experiments and instrument calibrations, exhibiting excellent consistency, high reliability, and good comparability. This dataset holds significant value for elucidating the reaction mechanism and structural evolution of composite Ru-based catalysts in acidic environments, and provides critical data support for the rational design and practical application of high-performance water electrolysis catalysts.
