摘　　要：水热炭作为糖类物质,因其具有良好的化学惰性、高堆积密度和优良的导热导电性能和独特的空间结构,被广泛应用于多个领域。为拓展水热炭材料(HTC)的应用研究领域,解决水热炭表面官能团单一、孔径、孔容难以调节等研究瓶颈,系统介绍了国内外水热炭材料的主要合成技术-水热法的基本现状及反应机理。阐述了水热炭在催化、吸附、放射医疗、核废物处理处置等领域的应用情况。基于壳聚糖为载体和离子印迹技术为平台的水热炭材料,是当前放射性核素吸附领域的研究热点之一。最后着重展望了水热炭在核素吸附领域的应用前景与发展方向。Recently, As carbohydrate substances, hydrothermal carbon, because of its excellent chemistry inertia, high packing density and good thermal conductivity and unique space structure has been developed dramatically in diverse fields. However,hydrothermal carbon also possesses some drawbacks,such as the single type of functional groups and adjustable pore size hardly that limit its performance. In order to broaden the application and solve the problem, herein a review on recent research progresses in the typical synthetic process of hydrothermat carbon. Moreover, hydrothermal method, the domestic and foreign development present situation and the research mechanism were summarized. The application of hydrothermal carbon in catalysis, adsorption, radiology and nuclear waste disposal were discussed. Chitosan-based ion imprinted technology was used for preparing hydrothermal carbon and this method had become one of the hot spots in current research about radioactive nuclide adsorption field. The future trend of application and development direction of the research was also pointed out.
