Coal⁃based activated carbon application is an important part of the clean and efficient use of coal. Basedon the characteristics of coal⁃based activated carbon with well⁃developed pore structure, stable physicochemical prop⁃erties, excellent adsorption performance, catalytic performance, easy regeneration and so on, it is widely used inmany fields. Therefore, it is of great significance to study and summarise the current status of the research and devel⁃opment trend of the application of coal⁃based activated carbon. This analysis consolidated recent Chinese research oncoal⁃based activated carbon, delineated its application characteristics in principal fields, and scrutinized its role inliquid phase adsorption (including water treatment, food processing, precious metal extraction, and pharmaceuti⁃cals), gas phase adsorption (like flue gas purification and volatile organic compound treatment), catalysis (cata⁃lysts, catalyst carriers, etc.), supercapacitors, electrode materials, soil amelioration, gas separation, cigarettefilters, and other areas. It also considered the future research direction for coal⁃based activated carbon in China.With its diverse uses in purifying municipal tap water, treating domestic and industrial sewage, pharmaceuticalwastewater, and more, coal⁃based activated carbon is of paramount importance. It also finds widespread use in foodprocessing for decolorization, deodorization, and purification, and is significantly utilized in extracting precious met⁃als like gold with activated carbon and purifying and decolorizing pharmaceutical intermediates. In gas phase adsorp⁃tion, its role in flue gas purification and volatile organic compound treatment showcases its technical application prow⁃ess and vast development potential. The current application of coal⁃based activated carbon in catalysis highlights itsintrinsic catalytic function in various reactions including oxidation, reduction, halogenation, dehydrogenation,cracking, isomerization, among others. It also serves as a catalyst carrier and can form complex catalysts by couplingwith other substances loaded on it to achieve a synergistic catalytic effect. Future research should focus on the produc⁃tion of varied types of coal⁃based activated carbon as per application requirements, substitutability studies of high⁃quality raw coal, development of novel binders for columnar activated carbon, exploration of activated carbon modifi⁃cation new type technologies, and the establishment of a standardized system for the activated carbon industry. As asignificant subdivision of new materials and carbon materials, coal⁃based activated carbon is poised to play a crucialrole in the sustainable development of our national economy.
