Scalable Synthesis of Atomically Dispersed Cu@Al2O3 Catalysts Accompanied by Chemical Looping Combustion Process for Reverse Water-Gas Shift Reaction

The structural characterization data in the dataset mainly includes XRD, XPS, BET, H2-TPR, CO2-TPD, SEM, TEM, and Cs HAADF-STEM characterization data. The data is used to support the atomic level dispersion of copper as the active ingredient on the catalyst support, and the continuous precipitation of metallic copper from CuAl2O4 spinel is a key factor in improving catalytic performance. Among them, XRD data was measured using a Rigaku SmartLab SE X-ray diffractometer with a scanning range of 2 θ=5-90 °; XPS data was obtained using a Thermo K-Alpha X-ray photoelectron spectrometer and corrected for binding energy with a C 1s peak; H2-TPR and CO2-TPD tests were conducted using a chemical adsorption apparatus; The N2 adsorption desorption data was obtained using a Micromeritics ASAP 2460 fully automatic physical adsorption instrument, with specific surface area calculated using the BET method and pore size distribution analyzed using the BJH model; SEM images and element distribution data were obtained using a ZEISS Sigma 360 field emission scanning electron microscope and its accompanying energy spectrometer; TEM images and element distribution data are provided by JEOL Obtained by JEM-F200 field emission transmission electron microscope; Cs HAADF-STEM image by JEOL Obtained by JEM-ARM 200F in-situ aberration correction transmission electron microscopy.
