Metal-organic framework (MOF) materials have significant advantages for capturing CO₂. To further improve the CO₂ adsorption performance of MOFs, a compound material of l-arginine modified graphene oxide (GO) with MOFs (MOF/GO-Arg) was synthesized. Introduction of amino acid-functionalized lamellar GO into MOF material not only generated new pores at their interface to improve the adsorption of the MOF but also promoted the CO₂ capture at low humidity. The structural and chemical properties of the parent components and composite materials were analyzed by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), N₂ adsorption-desorption, thermal analysis and scanning electron microscopy (SEM). The dynamic CO₂ adsorption properties of the materials were compared under different temperatures, flow rates and humidities. Three kinetic models were used to fit the adsorption curves of the as-synthesized adsorbents under different conditions, and then the optimal dynamic model was determined. Since the reusability of the adsorbents is especially important for the use of these materials in practice, the CO₂ adsorption was repeated for 10 cycles under optimal temperature, flow rate and high humidity conditions.

金属有机框架（MOF）材料在捕获CO _2方面具有显着优势。为了进一步提高MOF的CO ₂吸附性能，合成了1-精氨酸修饰的氧化石墨烯（MO）与MOF的复合材料（MOF / GO-Arg）。将氨基酸官能化的层状GO引入MOF材料中，不仅在其界面处产生了新的孔以改善MOF的吸附，而且还促进了低湿度下的CO ₂捕集。通过X射线衍射（XRD），傅立叶变换红外光谱（FTIR），N ₂分析母体成分和复合材料的结构和化学性质。吸附-解吸，热分析和扫描电子显微镜（SEM）。比较了材料在不同温度，流速和湿度下的动态CO ₂吸附性能。利用三种动力学模型拟合不同条件下合成吸附剂的吸附曲线，确定了最佳动力学模型。由于吸附剂的可重复使用性在实践中对于这些材料的使用特别重要，因此在最佳温度，流速和高湿度条件下，将CO ₂吸附重复10个循环。
