Zusammenfassung:	A carbon-based porous material microscopically exhibiting a three-dimension 1 cross-linked net-like hierarchical pore structure, a specific surface area of 500˜2,500 m2/g and a water contact angle greater than 90°. The surface of the carbon-based porous material has a through hierarchical pore structure with mesopores nested in macropores and micropores nested in mesopores, the content of mesopores is high, and there are more adsorption activity sites exposed on the surface of the material, so that the diffusion path for organic gas molecules in the adsorption process is shortened. At the same time, the absorption and desorption rates may also be accelerated and the desorption temperature may be lowered. Furthermore, benefits result for solving the desorption and recovery problems of organic gas molecules. Moreover, the defects of ordinary porous carbon materials being easily hygroscopic, having a weakened capacity to adsorb target gas molecules in a humid environment, etc. are further effectively solved.
