报告摘要:

High pressure NMR methods for the study of the kinetics of gas-solution reactions are presented and the importance/interplay of mass transport and chemical resistances discussed. For reactions that are slow compared to mass transport the true reactions kinetics can be obtained and used to confirm that the observed species are relevant to the catalytic reaction. Conversely, the ability to determine the catalyst speciation during the catalytic reaction aids interpretation of the kinetic data. The application of chemical shift imaging (CSI) techniques in combination with chemical gradients to characterize soft matter and to allow high throughput, combinatorial analysis of samples will also be discussed.

报告人简介:

After completing his PhD with Dr Martin Mays at the University of Cambridge, U.K. and a post-doc with Prof Bernard Shaw at the University of Leeds, Dr. Iggo joined the Faculty at the Queens University of Belfast as a “New Blood” lecturer before moving to the University of Liverpool where he is currently a Senior Lecture in the Department of Chemistry. With Prof. Heaton, Iggo set up the Liverpool High Pressure Spectroscopy Group. DrIggo's research interests are focused on in and ex situ and in operando studies of mechanism in organometallic catalysis; Iggo developed the world’s first, practicable, NMR system for studying working organometallic catalysts where one or more substrate is a gas and was closely involved in the development of the Lucite ALPHA Process for methyl methacrylate. Iggo also works with Xiao on understanding the mechanism of asymmetric hydrogens and transfer hydrogenations. More recently Iggo (with Wallace) has been developing chemical shift imaging with chemical shift gradients to study reactions occurring along a chemical gradient and has applied this technique to study the formation of gels and the interactions of guest molecules with the gel fibres.
