Dynamic in-situ (Operando) spectroscopy is a technological tool used to study materials' surface structure, reaction
kinetics and catalytic mechanism under real working conditions to reveal reaction mechanisms, evaluate catalytic
performance and shorten the design and development cycle of new materials. According to the concept of “reasonable
design and controllable preparation” of industrial catalysts, we focus on (1) Creating new strategies for the regulationof industrial catalyst structure assisted by in-situ spectroscopy (Operando) technology to study a real reaction
process; (2) Explaining the relationship of structure-activity of the active sites throughout the catalyst lifecycle(preparation-structure, structure-activity-product, deactivation-regeneration). (3) Acquiring the synergistic
regulation mechanisms for the process of preparation-activation-reaction-transfer in catalysts; (4) finally, greatly
improving the efficiency of research and development for the industrial catalysts. We have developed a new generationof Operando spectroscopy (reaction cell up to 50 bar). The combination of kinetics, DFT, and operando spectroscopy
allows us to build the relationship of structure-performance for the catalysts. The project aims to develop efficient
nanocatalysts that build on the atomic-level information obtained from our mechanism studies.
Prof. Yi-Fan Han received his PhD from East China University of Science and Technology (ECUST) with honors in1997. He worked as a postdoctoral fellow at the department of chemistry of Fudan University (Shanghai), the Catalysisand Surface Chemistry department of ULM University (Prof. R. J. Behm, Germany), and the chemistry department ofTexas A&M University (Prof. W. D. Goodman & Prof. J. H. Lunsfund, College Station, USA). From 2004 to 2009 he wasa senior research fellow at the Institute of Chemical and Engineering Sciences (A*STAR, Singapore). He has been at
East China University of Science and Technology (Shanghai, China) as a professor since 2009. He has published morethan 160 papers in top professional journals like JACS, Angew. Chem.-Int. Edit.,J. Catal, AIChE J., 7500 citations inSCI, 53 application for patents.
