Construction of Carbon Aerogel Monoliths and Their Application in Fine Separation of Coal Chemical Industry

Abstract

Carbon aerogels are three-dimensional porous materials with low density, large specific surface area, abundant pore structure, high electrical conductivity, chemical stability, environmental compatibility, tunable surface chemistry, and controllable structure. These properties give carbon aerogels excellent adsorption properties. Carbon aerogels are widely used in the treatment of various pollutants in coal chemical industry. Based on this, this paper reviews the construction of carbon aerogel monolithic materials and their application in fine separation of coal chemical industry. First, the construction strategies of carbon aerogels are introduced. Second, the application progress of carbon aerogels in fine separation of coal chemical industry is reviewed. The recovery and removal of high-value resources in coal-based liquid pollutants, solid wastes, and gaseous emissions are summarized. Finally, the present situations, problems, and perspects are analyzed.
