  报告内容简介:

  The selective oxidation can be effectively catalyzed using noble metal nanoparticles. Choosing an appropriate support with well-defined structure and suitable surface chemistry is a feasible and effective approach to make metal nanoparticles with specific size, shape, structure, and to avoid agglomeration leading to catalytic deactivation. With the intention of successfully synthesizing more efficient heterogeneous catalysts for the selective oxidation, it is extremely important to elucidate the effect of metal nanoparticle configuration, the novel nano-structured support on the catalytic activity for selective oxidation with particular highlights on the interactions between both metal-metal and metal-support. In this work AuPd and PtFe bimetallic, Pt and Ir monometallic catalysts and their applications in selective oxidation of HMF to FDCA were attempted. The unique structure of selected support is found to improve the stabilization of the metals in the preparation as well as the reaction process. Furthermore, surface chemistry (metal-support interaction) and synergetic effect in the case of metal alloy catalysts (metal-metal interaction) play a crucial role in controlling the catalytic performance of as-prepared catalysts. Various characterizations will be carefully conducted to look into the insights of these catalysts’ physicochemical properties.

  报告人简介:

  Dr. Yang received B.S. degree in chemical engineering from Tsinghua University and Ph.D. degree in chemical engineering from Yale University in 1998 and 2005, respectively. Yang joined the School of Chemical and Biomedical Engineering, Nanyang Technological University (NTU), Singapore as an assistant professor in August 2005 right after he graduated from Yale. Yang was promoted to be associate professor with tenure in chemical engineering in 2010. Dr. Yang’s primary research area is heterogeneous catalysis over metals and metal oxides, in particular, he is interested in understanding the fundamental catalytic concepts and phenomena using well-defined model catalyst and chemically probed reactions. Yang’s research was funded by MOE, Astar, NEA, NRF, and NTU in Singapore, he has published more than 200 research articles and attracted over 7700 citations, H-index 44. Yang joined the School of Chemistry and Molecular Engineering, Nanjing Tech University in 2017 as a full-time faculty member.
