摘要:
利用光催化技术将低密度的太阳能转化为高密度的化学能或直接降解有机污染物，是解决能源短缺和环境污染等问题的最理想途径。氮化碳是近期发展出来的一类聚合物半导体新型光催化剂，在分解水制氢、污染物降解、二氧化碳还原、选择性有机合成等研究方面有着重要科学意义和应用前景。前驱物超分子自组装法是制备高效纳米氮化碳光催化剂的重要合成方法之一。通过分子间的弱相互作用力，如三聚氰胺与三嗪衍生物之间的氢键相互作用，形成有序的超分子组装体，再进一步焙烧热聚合可制备氮化碳纳米材料。通过控制自组装过程的反应参数和条件，可以有效地调控氮化碳的组成、形貌、能带结构、光学性能、光生载流子分离效率，从而提高氮化碳的光催化性能。本文综述了超分子自组装法合成氮化碳光催化剂的最新研究进展，总结了系列纳米结构氮化碳光催化剂的研究工作，包括共聚合改性氮化碳、非金属掺杂氮化碳、金属掺杂氮化碳、金属氧化物-氮化碳复合物、氮化碳异质结以及高结晶度氮化碳光催化剂等。论文还阐述了超分子自组装法对氮化碳的组成、结构和光催化性能的调控作用，并展望了该研究领域的未来发展。
Abstract:
Converting the low-density solar energy into the high-density chemical energy or realizing the direct degradation of organic pollutants by photocatalytic technology is one of the important ways to solve the problem of energy shortage and environmental pollution. Carbon nitride is a polymeric semiconductor photocatalyst that shows important applications in water splitting, pollutant degradation, CO2 reduction and selective organic synthesis. Supramolecular self-assembly of precursors is one of the important synthetic methods of highly-effective nanostructured carbon nitride photocatalyst. Carbon nitride nanomaterials can be prepared by thermal polymerization of the ordered supramolecular aggregation formed by hydrogen bond interaction between the precursors of melamine and triazine derivative. By controlling the reaction parameters and conditions of self-assembly process, the composition, morphology, band structure, optical property, and electron-hole separation efficiency of carbon nitride can be effectively tailored, thus improving the photocatalytic activity of carbon nitride. Herein, the latest research progress concerning the supramolecular self-assembly synthesis of carbon nitride photocatalysts is reviewed. The work of nanostructured carbon nitride photocatalyst is summarized, including copolymerization modified carbon nitride, nonmetal doped carbon nitride, metal doped carbon nitride, metal oxide and carbon nitride composite, carbon nitride based heterojunction, and highly crystalline carbon nitride photocatalyst. The effect of supramolecular self-assembly method on the composition, structure, and photocatalytic activity of the carbon nitride is also illustrated. The future development direction of this field is indicated.
