摘要
介绍了碳气凝胶的制备工艺，全面综述了碳气凝胶在吸附、保温、催化、超级电容器、储能等领域中的主要研究进展。碳气凝胶是一种新型非晶态有机纳米材料，单位比表面积高（400~3 000 m2/g）、孔隙率高（80%~99%）、具有超低的热导率，在吸附、相变保温材料中有重要应用。碳气凝胶强度大、稳定性好、具有丰富的反应位点，这些因素决定了它是优秀的催化剂载体；同时碳气凝胶还展现出有机气凝胶所没有的优秀导电性。
Abstract
Preparation process for carbon aerogels is introduced.Main research progress on applications of carbon aerogels in the fields of adsorption,heat preservation,catalysis,supercapacitor and energy storage is comprehensively reviewed.Carbon aerogel is a new type of amorphous organic nanomaterial with high specific surface area (400-3 000 m2·g-1),high porosity (80%-99%) and ultra-low thermal conductivity.It has important applications in adsorption and phase change thermal insulation materials.Carbon aerogel is an excellent catalyst carrier due to its higher strength,good stability and abundant reaction sites.Furthermore,carbon aerogels also show excellent electrical conductivity that organic aerogels do not.
