摘要
金属氧化物作用下的催化燃烧可有效消除挥发性有机物(VOCs),工业前景较好,目前研究重点在于开发适宜结构的载体。石墨相氮化碳(g-C_3N_4)结构稳定,电子性能独特,其供电子特性与表面碱性位均具有促进氧气与反应物分子活化的潜能,有望成为VOCs催化燃烧催化剂的优良载体。介孔结构能改善电子特性,提高活性组分分散,促进反应物扩散,将成为g-C_3N_4研发的主要方向。
Metal oxide catalyzed volatile organic compounds（ VOCs） combustion which can effectively eliminate VOCs,is developed as an air pollutant treatment technology with industrial application prospects. Support materials with suitable structure are of great importance. Graphitic carbon nitride（ g-C3N4） is a unique material with stable structure and electronic properties. Its electron donating property and surface basicity have the potential to promote the activation of oxygen and reactant molecules. It is expected to become an efficient support of metal oxide catalyst for the catalytic combustion of VOCs. The mesoporous structure has the characteristics of improving the electronic properties of g-C3N4,the dispersion of active components and promoting the diffusion of reactants,which will become the main direction for the development of g-C3N4 structure.
