摘　　要：水热炭材料作为一种新型碳材料,具有含氧官能团丰富、堆积密度高、热稳定性强和导电导热性优良等特点,在催化和吸附、储能材料领域具有潜在的应用价值,尤其适用于吸附各种污染物。首先介绍了水热炭的分类和制备,根据尺寸可以分为水热炭量子点和水热微球。其次综述了水热炭的酸洗改性、碱洗改性、官能团化改性以及对污染物的吸附性能和机理。改性水热炭对污染物吸附的机理包括物理吸附和化学吸附,其中物理吸附主要由范德华力所引起的分子间作用,化学吸附主要包括络合配位、离子交换、静电吸引、氧化还原反应等;最后针对水热炭现存问题进行讨论与展望,以期为改性水热炭吸附去除污染物的广泛应用提供理论支撑。As a new type of carbon material,hydrothermal carbon material has the characteristics of rich oxygen-containing functional groups,high accumulation density,strong thermal stability and excellent thermal conductivity.It has potential application value in the field of catalytic and adsorption and energy storage materials,especially suitable for the adsorption of various pollutants.Firstly,the classification and preparation of hydrothermal carbon can be divided into quantum dots and microspheres according to their size.Secondly,the pickling and modification,alkali washing,functional formation and adsorption properties and mechanism of hydrothermal carbon were reviewed.The mechanism of pollutant adsorption includes physical and chemical adsorption.Physical adsorption is mainly caused by the van der Waals force,and chemical adsorption mainly includes complexation coordination,ion exchange,electrostatic attraction,redox reaction,etc.Finally,the existing problems of hydrothermal carbon were discussed and expected to provide theoretical support for the wide application of modified hydrothermal carbon adsorption to remove pollutants.
