Project:Solid State Nuclear Magnetic Resonance Methods for Studying Heterogeneous Catalysis

Chief Specialist: Prof.Feng Deng

Abstract:

    This project focuses on the investigation of important scientific issues of structure-property relationship in heterogeneous catalysis and the basics of catalysis. The solid-state NMR methodology will be developed for the studies of active sites, host-guest interaction and catalytic mechanisms in heterogeneous catalysis. Developing new NMR method will be carried out for the observation of the metal nuclei with ultra-wide linewidth and the sensitivity enhancement of the low gamma nuclei, with the aim to reveal the structure of the active sites. New 1D and 2D NMR methods will be developed to characterize the host-gust interactions for establishing the spatial proximities/interactions between reactants, reactive intermediates and products with catalyst support and active sites. On the basis of dynamic nuclear polarization (DNP), the signal enhancement NMR technique will be developed to design and prepare new polarizing agents on catalyst and establish DNP-NMR methods for studying heterogeneous catalytic reaction mechanisms. Some important reactions are to be studied over zeolites and oxide catalysts, to reveal catalytic reaction mechanisms of methanol to olefins and activation and conversion of light alkanes, which will provide insights in the design of robust catalysts and the development of new catalytic processes. The objective of this project is to establish a set of advanced solid-state NMR methods to promote the application of solids-state NMR in the fields of heterogeneous catalysis and material sciences.
