Aerogel is a special type of porous material with many outstanding physical and chemical properties, such as low density, high porosity, high surface area, and adjustable surface chemistry. Thanks to the latest advances in the synthesis of different types of aerogels, the feasibility of this porous material in several applications has been widely explored. In a variety of high performance applications, aerogels have received much attention as an adsorption medium that removes a variety of environmental and human health pollutants. Although the performance of aerogels in environmental sanitation is encouraging, some shortcomings of aerogels, such as complex drying process, mechanically fragile structure and processing costs, have also been taken into account and have been taken into account been determined in some studies. Degree of relief. This review article aims to describe the synthesis and processing of aerogels and their latest applications in air purification, such as carbon dioxide capture and VOC removal, as well as applications in the treatment of air, water, including oils and toxic organic compounds and heavy metals ion removal.

气凝胶是一种特殊类型的多孔材料，具有低密度、高孔隙率、高表面积和可调表面化学等许多优异的物理和化学性能。由于不同类型气凝胶合成的最新进展，这种多孔材料在多种应用中的可行性得到了广泛的探索。在各种高性能应用中，气凝胶作为一种去除各种环境和人类健康污染物的吸附介质而备受关注。尽管气凝胶在环境卫生方面的表现令人鼓舞，但气凝胶的一些缺点，如干燥过程复杂、机械脆弱的结构和加工成本，也已被考虑在内，并在一些研究中被确定。缓解程度。
