报告摘要：
The mechanisms of catalytic transformations over solid catalysts as well as the mechanisms of their synthesis were always a source of controversy in heterogeneous catalysis and there are still a lot of discrepancies between different mechanistic proposals. To get deeper insightthe mechanisms, application of the in situ techniques, which allow directobservation of the reactant and the catalyst under “working” conditions ishighly desirable. Among such techniques, in situ NMR is considered to be one ofthe most informative. The aim of this lecture is to review the advances in thein situ MAS NMR and to analyze the impact of this technique to the unravel ofthe mechanisms of zeolite catalyzed reactions and synthesis of zeolite likesolids.
The first part of the lecture will contain brief information on different experimental approaches used for in situ MAS NMR studies under batch and flow conditions of catalytic transformations as well asunder the conditions of hydrothermal synthesis of solid materials. In the second part, the capabilities of the techniques and its main application areas will be briefly reviewed. The emphasis will be made on the reactions, for whichin situ MAS NMR was of particular help for the understanding of reaction mechanisms. In particular, the impact of the in situ MAS NMR to the unravel of the mechanisms of olefins, alcohols and alkanes transformations over zeolite catalysts will be analyzed. Finally, in the last part the recent advances in the investigation of hydrothermal synthesis of zeolites will be discussed.
