2026-09-16 RuCo Alloy Nanoparticles Supported on Mesoporous Hollow Carbon for Efficient Chlorine Evolution Reaction doi:10.57760/sciencedb.j00125.0009j en This dataset is derived from the research work entitled “RuCo Alloy Nanoparticles Supported on Mesoporous Hollow Carbon for Efficient Chlorine Evolution Reaction” and mainly contains structural characterization, physicochemical properties, electrochemical chlorine evolution reaction (CER) performance, stability, and chlorine evolution selectivity data of RuCo alloy nanoparticles supported on mesoporous hollow carbon (RuCo-MHC) and the corresponding control samples. The data were obtained through experimental measurements, including field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), nitrogen adsorption–desorption, inductively coupled plasma optical emission spectrometry (ICP-OES), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, and electron paramagnetic resonance (EPR) spectroscopy. Electrochemical data, including linear sweep voltammetry (LSV), cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and chronoamperometry, were collected using a Gamry Reference 3000 electrochemical workstation. Electrochemical measurements were conducted in a three-electrode configuration using 5 M NaCl electrolyte at pH=2. The potentials were converted to the reversible hydrogen electrode (RHE) scale, and 95% iR compensation was applied. The Faradaic efficiency for chlorine evolution was determined by iodometric titration.The dataset includes numerical data such as current density, potential, overpotential, Tafel slope, EIS parameters, double-layer capacitance, electrochemically active surface area (ECSA), specific surface area, pore volume, pore-size distribution, elemental composition, XPS binding energies, lattice spacings, and Faradaic efficiency for chlorine evolution. Current density is mainly expressed in mA cm-2, potential in V vs. RHE, overpotential in mV, and specific surface area in m2 g-1, while elemental composition is expressed in wt%. The units of other parameters are specified in the corresponding data files. The data were processed through potential conversion, iR compensation, Tafel fitting, ECSA calculation, and Faradaic efficiency calculation. Selected experiments were performed with repeated measurements to evaluate data reproducibility. Experimental uncertainties mainly arise from sample preparation, electrode preparation, and instrumental measurements. The dataset files mainly contain characterization and electrochemical measurement data, which can be further processed and analyzed using software such as Origin and Microsoft Excel.
