Project: in situ solid state NMR and zeolite catalysis

Chief Specialist: Prof.Jun Xu

Abstract:

    The applicant has been conducting the research on the development and application of in situ solid state NMR technique to heterogeneous catalysis. Focusing on the C1 chemistry(e.g., methane, CO and methanol) on zeolite catalysts, he performed systematic studies on the catalytic reaction mechanism of C1 molecules by using various in situ solid-state NMR methods. He revealed (1) the C-H bond activation and conversion mechanism in methane under mild condition as well as the methane carbonylation mechanism, (2) CO oxidation mechanism on non-noble active sites and CO co-reaction mechanism, and (3) the ‘hydrocarbon pool’ mechanism for the formation of ethene and propene in the conversion of methanol to olefins, confirmed the supramolecular reaction center and revealed its catalytic role in the reaction. He has published 31 papers in SCI-indexed journals including J. Am. Chem. Soc., Angew. Chem. Int. Ed., Chem. Sci., etc. He has been the principal investigator of 4 grants from
‘National Natural Science Foundation of China’ and 2 projects found for fostering talents.
