In recent years, the concentration of greenhouse gases, mainly CO2, in the atmosphere continues to increase, which leads to theincreasing greenhouse effect. Carbon dioxide capture, utilization and storage (CCUS) is the bottom technology to achieve carbon neutrality, and the cost of carbon dioxide capture accounts for about 70% of the whole CCUS chain. The development of low-cost carbon dioxide capture technology is the top priority to promote the application and promotion of CCUS technology. While researchers have developed avariety of advanced materials (such as zeolites, metal-organic frameworks, mesoporous silica, and polymers) to cope with CO2 capture,research on activated carbon (ACs) is still mainstream. Carbon material has the advantages of wide source, low price, abundant porestructure, stable physical and chemical properties, etc. It is a kind of carbon dioxide adsorption material with great application potential.The existing carbon-based adsorption materials still have the disadvantages of low carbon dioxide adsorption capacity and poor adsorptionselectivity, which restricts their application in the field of carbon dioxide capture. Researchers at home and abroad have carried out a lotof modification work of carbon-based adsorption materials to meet the needs of industrial applications. The research progress at home andabroad in recent years was introduced by combing the two aspects of carbon-based adsorption material pore-making and surface modification. The existing pore-making methods such as physical activation method, chemical activation method, template method and surface oxidation, nitrogen hybrid, sulfur hybrid and metal hybrid modification methods were summarized, and the advantages and disadvantages ofdifferent methods were comprehensively analyzed. In view of the current pore-making technology, the soft formwork agent with lower costand the hard formwork agent with easier processing are considered. Among many modification methods, nitrogen hybrid modificationand metal hybrid modification are studied more, and they are also one of the most likely ways to achieve large-scale production of carbonbased adsorption materials.
