英文摘要： This project aims at studing on the preparation of new carbon materials with high-speed proton-exchange passage. Facing at the food security and the environmental protection, the structural design and performance improvement of novel functionalized carbon materials for high proton conductivity is performed to construct new electrochemical sensors for the determination of pollutant analysis. The new carbon materials with high-speed proton-exchange passage are prepared by the heteroatom doping, the controlling of oxygen-containing groups, the proton doping and the combination with original proton conductor. The influence of high-speed proton-exchange on the electrode reaction of pollutants is performed to explore the role of proton passage during the catalysis process. Based on the obtained mechanism, sensors with high sensitivity, high response speed, and high selectivity are constructed for the determination of regular pollutants. Based on the research of structure-performance relationship, the high-performance electrochemical sensors are prepared, and the application of materials with low electron conductivity are explored. In all, the project is favor to extending the material selection in the construction of pollutants sensors, and the research substratum of carbon based proton conductor are provided by the project.
