Abstract

Abstract

In order to promote the in-depth development of CO₂ conversion and utilization technology and facilitate the smooth implementation of the "dual carbon" policy, this paper has conducted a series of experimental studies on CO₂ hydrogenation to methane based on the modulation of perovskite composite catalysts through basic research. Through comparison, the influence of catalyst composition factors on catalytic performance was investigated. Through a single factor variable experiment, the relationship between operational factors and catalytic performance was investigated in detail. The microstructure of the catalyst was analyzed and characterized in detail using analytical methods such as XRD, BET, SEM, CO₂-TPD, XPS. The impact of catalyst physicochemical properties on catalytic activity was analyzed, and the positive role of doping Mg in perovskite type catalysts in regulating CH₄ selectivity was clarified. The results show that La_0.9Mg_0.1Co_0.5Ni_0.5O₃ catalyst has excellent catalytic performance at atmospheric pressure, and can achieve nearly 100% CH₄ selectivity in the temperature range of 350 ℃ to 500 ℃. Through characterization methods, it has been proven that the doping of Mg can provide more CO₂ adsorption sites, which plays an important auxiliary role in improving catalytic performance.
