Summary

Aerogel is a special 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, this porous material's feasibility in several applications has been widely explored. In a various 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 determined in some studies degree of relief. This review chapter aims to describe the synthesis and processing of aerogels and their latest applications in air purification, such as carbon dioxide capture and volatile organic compound (VOC) removal, as well as applications in the treatment of air, water, oils and toxic organic compounds, and heavy metals ion removal.
