As global climate warming and environmental issues becoming increasingly severe,CO2 emission reduction and resource utilization have become focal points in academic research.This study focused on optimizing the performance of Fe-based catalysts in CO2 hydrogenation reactions,particularly the impacts of carrier surface functional groups on catalytic activity and product selectivity.Through the hydrothermal synthesis,nanocarbon spheres with different surface microenvironments were synthesized,and by combining with the equal-volume impregnation method to load metal active components and promoters,a series of Fe-based catalysts were successfully prepared.The catalysts were characterized by scanning electron microscopy (SEM),X-ray Diffraction (XRD),transmission electron microscopy (TEM),X-ray photoelectron spectroscopy (XPS),and in-situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS),and the results revealed that the carrier surface functional groups had a significant impact on the CO2 conversion and product selectivity,providing new insights for designing efficient and stable Fe-based catalysts.
