Abstract:Due to the dual roles of CO2 as a main greenhouse gas and a renewable C1 carbon source,research on CO2 adsorption and separation is of great importance to both academic interests,and social and economic progresses.Based on various kinds of porous materials with distinct structural parameters,this paper reviews the recent development of novel porous CO2 sorbents and their sorption behavior.Porous carbons possess controllable micro/macroscopic morphology,tunable pore structure and good stability.Molecular sieves have rich microporosity with concentrated pore size distribution.Metal-organic frameworks and porous polymers offer a great variety of products,representing newly emerging CO2 capture materials.In addition,key issues on structure effect of new sorbents on high efficiency CO2 capture under actual conditions are discussed.Finally,perspectives on how to design the composite and the quantitative analysis of pore structure contributing to sorption capacity are provided.
