Abstract:

Global warming caused by greenhouse gas emissions is a pressing environmental problem. Given that CO2 is the most significant greenhouse gas, research into materials that can efficiently adsorb CO2 has attracted considerable attention. Compared with other adsorption materials, porous materials offer a large specific surface area with high chemical and thermal stabilities and also feature good adsorption capacity, selectivity, cyclicity, and fast adsorption kinetics; therefore, they are widely used as solid adsorbents for CO2 capture. This review systematically introduces five types of porous carbon materials coal/petroleum-coke-activated carbons, biomass porous carbons, carbon aerogels, metal-organic-framework-derived carbons, and carbon nanomaterials that have been developed in recent years. Furthermore, the four primary methods used to prepare these materials for CO2 adsorption (i.e., high temperature carbonization and activation, hydrothermal carbonization, sol-gel processing and the template method) are presented. Emphasis is placed on their structure-performance relationship with CO2 adsorption. Simultaneously, the mechanism whereby CO2 is adsorbed by porous carbons with a pore texture is reviewed, in addition to the surface chemistry. Lastly, current challenges pertaining to CO2 adsorption are summarized, and future development trends are also prospected.
