摘要
SiO_(2)气凝胶具有高孔隙率、良好的吸附能力和表面易改性等优异特性,在污水和空气净化等领域具有极大的应用前景。近年来,城市温室效应加剧、空气质量下降,亟待开发新一代高效空气净化材料。从温室气体吸附和气相有毒化合物吸附两个应用背景出发,总结了SiO_(2)气凝胶的吸附原理和改性工艺,概述了众多学者在该领域的研究成果,并对未来研究方向提出了展望。
Silica aerogel has excellent properties such as high porosity,good adsorption capacity,and easy surface modification.It has great application prospects in the fields of wastewater treatment and air purification.In recent years,the urban greenhouse effect has intensified and air quality has declined.There is an urgent need to develop a new generation of highly efficient air purification materials.From the two application backgrounds of greenhouse gas adsorption and gas phase toxic compound adsorption,the adsorption principle and modification process of SiO_(2) aerogel were summarized,the research results of many scholars in this field were outlined,and finally an outlook on the future research directions of further research were provided.
