| Summary: | Carbon aerogels (CAs), owing to their low density, rich pore structure, high specific surface area, and excellent physicochemical stability, possess broad application prospects in the field of pollutant adsorption/absorption in aqueous‐phase systems. Starting from the various performance indicators, such as capacity, efficiency, reusability, and selectivity of CAs applied in aqueous adsorption/absorption scenarios, the structural compositions and intrinsic characteristics, including wettability, activity, porous structure, macroform, and mechanical property, of CAs that affect these properties are analyzed and traced. Besides, the construction paths of CAs with different characteristics from the perspectives of precursor selection (polymer, biomass, and graphene), preparation processes (gelling, drying, and carbonization), and modification methods (doping, compositing, and coating) are further summarized. From this, the generalized interrelationships among the structures, properties, and applications of CAs adsorbents are clarified, and the specific methods for the design and regulation of CAs are provided. Thus, this review lays a theoretical and practical foundation for the oriented production of efficient CAs suitable for specific aqueous adsorption/absorption scenarios and for the energetical promotion of CAs adsorbents toward commercial market applications. |
