New breakthroughs in Fudan catalytic control technology

A few days ago, it was learned from Fudan University that the Tang Xingfu Group of the Department of Environmental Science and Engineering of the university achieved a new breakthrough in catalytic control technology, successfully resolved the nature of metal-carrier interactions, and constructed an electronic state structure of metal monoatomic active sites. The structure-activity relationship between the catalytic activity and the atomic electron state solves some key environmental catalysis problems in depth. The results of the relevant research are published as an in-house cover article published online in Applied Chemistry in Germany.

In recent years, the emission of volatile organic compounds in China has continued to increase, and the concentration of PM2.5 and O3 in the atmosphere has remained at a high level. The resulting air pollution has caused great harm to the ecological environment and human health.

In order to reduce the occurrence of haze and improve regional air quality, it is necessary to control the emission of volatile organic compounds, which are precursors of PM2.5 and other atmospheric pollutants, at the source. Among the many VOC emission control technologies, the highly efficient and environmentally friendly catalytic control technology with no side effects has attracted widespread attention. As the core of the catalytic control technology, the catalyst has become the top priority of research.

The research team led by Tang Xingfu cooperated with laboratories at home and abroad and used a variety of advanced testing methods to finally construct the structure-activity relationship between the electron state structure and catalytic activity of the metal monoatomic active sites, revealing the interaction between metal and carrier. Essentially, it also addresses some of the key environmental catalysis problems from the atomic electronic level.

Industry experts believe that the nature of the metal-support interactions revealed by the monoatomic silver catalysts not only has a large scientific theoretical value in the field of environmental catalysis, but also has a positive impact on the governance of the source of volatile organic compounds, as well as an atomic economy. The environmental protection catalyst represents a certain degree of practical guidance for the improvement and development of catalytic control technology.
