Progress in preparation and CO2 adsorption properties of solid waste-based sulfur-doped porous carbon materials
Carbon-containing solid wastes have a wide range of sources as well as large output,which seriously restricts the sustainable development of the environment.Therefore,the resource utilization of carbon-containing solid waste is of great significance.The preparation of porous carbon from carbon-containing solid wastes is one of the most important ways to utilize them cleanly and efficiently.Sulfur atom doping of porous carbon can not only improve the hydrophilicity of the material surface,but also changes the chemical heterogeneity,and then generates active sites favorable for CO2 capture,strengthens the adsorption performance of CO2 molecules by the material,thus increases the adsorption capacity of CO2.This paper briefly describes the preparation method of solid waste-based sulfur-doped porous carbon materials,summarizes the latest research progress of sulfur-doped porous carbon materials for CO2 adsorption,and looks forward to the future development trend of sulfur-doped porous carbon materials and their industrialized application in the field of CO2 adsorption.
