2025-03-10 Dataset on the Fabrication and Performance of Fe2N/Fe3C heterostructure embedded in Fe-N-C anchored carbon nanofiber synthesized doi:10.57760/sciencedb.j00125.00092 en This dataset provides a comprehensive record of experimental data related to the fabrication, characterization, and performance evaluation of Fe2N/Fe3C heterostructures loaded with Fe-N doped carbon nanofibers. The data include material preparation, structural characterization, oxygen-reducing and carbon dioxide-reducing property tests, and stability analysis. The materials were fabricated using electrostatic spinning technology. The dataset includes X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, scanning electron microscopy (SEM), ORR electrochemical properties, and CO2RR electrochemical properties.The dataset contains the following key components:Material Preparation Parameters: Spinning Solution Composition, Electrostatic Spinning Machine Setup Parameters, Heat Treatment Temperature and Duration.Structural Characterization Data: Scanning Electron Microscopy, Transmission Electron Microscopy, X-ray Diffraction Analysis, Raman Spectroscopy and X-ray Photoelectron Spectroscopy.ORR electrochemical performances data: LSV curves of ORR, half-wave potential, Tafel slope, LSV curves at different rotational speeds, K-L plots at different voltages, and relative rate of change of current density with time at constant voltage.CO2RR electrochemical performances data: LSV curves of CO2RR, Faraday efficiencies under CO and H2 conditions, curves of Faraday efficiency and current density versus time for certain conditions, comparison of Faraday efficiency and current density with comparison samples.
