Abstract：The biochar has been regarded as an excellent catalyst carrier with promising application prospects in the area of environmental pollutant degradation and organic synthesis, due to its environmental friendliness and rich raw materials. However, the intrinsic catalytic capability of the biochar cannot satisfy the demand in some specific applications. To address this challenge and enhance the catalytic capability of the biochar, many activation methods were involved, including the acid activation, alkaline activation, gas activation, plasma activation and metal impregnated activation methods. In this study, the effects of different activation methods on the pore distribution, specific area, active group, density of active sites, and catalytic capability of the biochar were compared. Additionally, applications of the biochar activated by different methods were discussed. This paper could provide references for the design of customizing biochar and its future applications.
