Prof. Wang Weichao of Nankai University was invited to give an academic report

At the invitation of my research group, Prof. Wang Weichao of Nankai University visited our school in the afternoon of December 18th and made an address for “Identifying descriptor of governing NO oxidation on mullite Sm(Y, Tb) Mn2O5 for diesel exhaust cleaning. "The academic report.

In this report, Professor Wang focused on the theme of mullite cleaning and catalyzing nitrogen and oxygen pollutants in lean burners. First of all, we introduced the advantages and disadvantages of diesel engines and the importance of developing catalysts for cleaning exhaust gas from diesel engines. This laid the foundation for further research on the entire system. Then he introduced some of his previous work's inspirations for his own research and tried it. Finally he discovered the great benefit of this important substance of mullite for the catalysis of nitrogen oxides in lean burn engines and simulated calculation of this kind of substance. And the electronic structure characterization also provides a basis for its catalytic mechanism, has an important value for the replacement of precious metals, and ultimately can be published in the "Science" because of the significance of this work. Finally, Professor Wang Weichao had a warm and friendly interaction with the teachers and students present here.

Wang Weichao, Bachelor of Physics, Henan Normal University; Master of Condensed Matter Physics, Institute of Solid State Physics, Chinese Academy of Sciences; Ph.D., Department of Materials Engineering, University of Texas at Dallas, USA. In 2013, he was appointed as a professor at the School of Electronic Information and Optical Engineering of Nankai University, and was the leader of the research group for the design and regulation of new functional materials. In the same year, he was selected as the National “Years of Thousand Talents Program”. The key scientific issues such as cleaning catalysts, surfaces and interfaces of III-V semiconductors are studied. The main academic results are: (1). Clean Catalyst Research: The successful development of manganese-based oxides is an ideal alternative to expensive platinum catalysts. , has been published in the "Science". (2). Interface and surface studies of III-V materials: The surface and interface of III-V semiconductors were systematically studied. The physical mechanism of Fermi pinning was found and a corresponding passivation scheme was proposed. (3). Photodegradation of water in heterojunctions: Heterojunction In principle, the advantages of two single-phase materials are combined to form an excellent photocatalytic carrier.
