碳材料和碳氮材料被认为是一种有望广泛应用于污染控制领域的新型非金属材料。他们具有比表面积大,吸附能力强的优点，常作为金属催化材料的载体使用，起到增加对目标物的吸附，促进催化反应发生的作用。金属材料价格相对昂贵、在反应过程中容易溶出而危害环境。如果能够用非金属，例如碳材料和碳氮材料，完全替代金属，实现对目标反应的高效催化，将有效降低污染物控制过程的成本并提高处理过程的环境安全性。因此，本项目拟借助多功能复合材料的优势，拟通过构建以多级结构的g-C3N4/C复合材料为主的少用甚至不用金属的新型复合催化剂，借助复合掺杂等手段，来提高污染物的催化降解效率和催化降解成本，有效的促进其在光催化领域和热催化领域的应用。这将有助于开发高效低成本环境友好型碳材料及碳氮材料的工业催化剂，促进其在污染控制领域的应用。

Carbon and carbonitride materials are considered as novel types of non-metallic materials which can be widely used in the field of pollution control. Owing to their remarkable large surface area and strong adsorption capacity, carbon and carbonitride materials are widely used as substrates for metal catalytic materials, served for increasing the adsorption of target reactants and promoting catalytic reaction. Metal materials are relatively expensive, and easily dissolved in the reaction process, resulting in harming the environment. If we can use non-metallic, such as carbon and carbonitride materials to replace metal materials completely, will expect to achieve catalytic reaction and reduce the cost of pollution control process efficienlly as well as improve the environmental security of the process. Therefore, this project intends to take advantage of the multifunctional composite materials, building with hierarchical structured carbonitride/carbon (g-C3N4/C) composite catalytic materials, which were mainly composited of carbon and carbonitride materials with less or without noble metal phase. By means of compositing and doping, the improved efficiency and reduced cost of visible light degradation of pollutants were achieved.achieved improved applications in the field of photocatalysis and thermocatalysis. These results are expected to develop efficient, low-cost and environment-friendly carbon and carbonitride catalytic materials, as well as to promote their applications in the field of pollution control.
