【Abstract】 The acceleration of industrialization has led to a continuous increase in CO₂ emissions, resulting in a profound impact on global climate change. Developing efficient CO₂ adsorbents is great significance for reducing industrial emissions and atmospheric CO₂ concentrations. Metal-organic frameworks（MOFs） have been extensively studied due to their high specific surface area and tunable pore structures. However, pure MOFs often suffer from insufficient stability in practical applications. Graphene oxide（GO）, on the other hand, is highly regarded for its excellent mechanical properties and chemical stability. In this study, a composite material of metal-organic framework（MOF-5） and graphene oxide（GO） was successfully synthesized via solvothermal synthesis. Comprehensive structural and morphological characterizations of both the parent materials（MOF-5 and GO） and the nanocomposite were conducted using XRD, SEM, TEM, FTIR, and nitrogen adsorption-desorption techniques. The CO₂ adsorption performance of these materials was also tested under dynamic conditions to evaluate their potential for practical applications. The results showed that the composite material exhibit a unique layered structure and retained the original characteristics of MOF-5 and GO. Compared with pure MOF-5, the CO₂ adsorption capacity of the composite is significantly enhanced by 42.07%.更多还原
