Amino-modified mesoporous carbon material for CO2 adsorption in tunnel engineering: materials characterization and application prospects

摘要: Developing efficient materials for capturing and storing CO2 is crucial in addressing the environmental crisis caused by excessive CO2 emissions. This paper presents the synthesis of amino-modified mesoporous carbon materials with high specific surface areas and efficient adsorption capabilities. The materials were synthesized using resol as the carbon source, F127 as the soft template agent, dicyandiamide as the amino-modified material, and a mixture of ethanol and water as the solvent. The structure and morphology of the amino-modified mesoporous carbon materials were characterized using N2 adsorption/desorption, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and transmission electron microscopy (TEM). The CO2 adsorption performance and mechanism of the materials were also investigated. The potential application of amino-modified mesoporous carbon materials in …
