摘要
氧化锆(ZrO_(2))气凝胶材料是以ZrO_(2)为主体、具有三维交联网络结构的纳米多孔材料,具有酸碱双性、氧化还原性、高比表面积、高孔隙率及良好的热稳定性和化学稳定性等特点,在隔热、催化、吸附、储能等领域具有广泛的应用。总结了ZrO_(2)湿凝胶的制备工艺及其干燥方法,从掺杂改性和二元复合两个方面介绍了国内外ZrO_(2)基气凝胶改性方面所取得的突破性进展,综述了ZrO_(2)气凝胶材料在隔热、催化和吸附领域的最新研究和应用,最后,对ZrO_(2)气凝胶的未来发展方向进行了展望。
ZrO_(2) aerogel is a kind of nano-porous material with a 3D cross-linked network on the main body of ZrO_(2).Because of its acid-base duality,redox property,high specific surface area,high porosity,and good thermal and chemical stability,ZrO_(2) aerogel has a wide range of applications in thermal insulation,catalysis,adsorption,energy storage,and other fields.In this paper,the preparation process and drying method of ZrO_(2) wet gel were summarized.The representative studies and research progress of ZrO_(2)-based aerogel modification were introduced from the aspects of doping modification and binary compounding.The research advances on ZrO_(2) aerogel materials in the fields of heat insulation,catalysis,and adsorption was reviewed.Finally,a prospect on the future research of ZrO_(2) aerogel was given.
