Excessive anthropogenic CO2emissions lead to global warming, which will have a serious impact on climate change in the 21st century. Flue gas carbon capture and Direct Air Capture (DAC) can directly reduce the concentration of CO2in the environment, which is critical to achieving the goals of the Paris Agreement. At present, carbon capture technology is mostly used for solution absorption and solid adsorption, and adsorption is widely used because of its cost effectiveness and technology maturity. However, an important challenge for CO2adsorption and separation is the limited diffusion and reaction kinetics of CO2in the active microenvironment of porous materials. This limitation hinders the balance between adsorption capacity and selectivity of materials in the carbon capture process. Therefore, the main challenge of adsorption technology is to develop a suitable adsorbent for CO2capture. It is usually possible to improve the adsorption capacity of CO2by controlling the pore properties and surface chemical properties of materials. This paper examines the current state of development of porous materials for carbon capture by reviewing the types of porous materials and case reports. The effect of precise adjustment of pore space and pore environment on CO2capture was discussed by studying pore structure and functional groups of porous materials. |
