摘要

Abstract

Aerogels are 3D porous materials with broad applications in various fields due to their structural characteristics and physicochemical properties. In recent years

aerogels are getting more and more attention as the unprecedented global pressure of the energy and environmental problems grows. As porous materials with high surface area and specific functional groups

aerogels are ideal to be used to preferentially adsorb certain toxic molecules or ions in the air and water. Such selectivity is achieved by material design

such as pore size control in the aerogel synthesis and/or by surface functionalization during and after synthesis. Certain aerogel compositions have been patented in recent years but their applications in the areas of adsorption remain very limited. After a brief introduction of the aerogel development history and general properties

this perspective highlights the recent progress in the development and mechanistic studies of adsorptive aerogels

and potential application of carbon- and silica-based aerogels as adsorbents in environmental remediation and healthcare areas

such as volatile organic compound (VOC) adsorption and hospital settings as air purification and sterilization. We also discussed gaps and recommended future studies as well as challenges in the fields. It is also apparent that more information is needed for a better understanding of the structural implications of the aerogels in specific pollutant adsorption and applications.
