Journal of the American Chemical Society has published yet another paper written by members of the JU Zeolites Chemistry Group, Prof. Kinga Góra-Marek and Dr Karolina Tarach, entitled Molecular Understanding of the Catalytinc Consequence of Ketene Intermediates under Confinement. The publication is a result of collaboration with the Chinese Academy of Sciences Innovation Academy for Precision Measurement Science and Technology.
The paper is focused on the research on the transformation of ketene, which is a key intermediate of many processes that lead to formation of C-C bond. It was proved that transforming ketene into wanted or unwanted intermediates depends upon the presence of certain elements of zeolite catalyst structures. These elements, due to the containment effect, allow for creation of metastable acylium ions that steer reactions toward desirable results, simultaneously leading away from undesirable path of catalyst deactivation. This, in turn, proved the impact the confinement effect on the formation, fate, and catalytic consequence of the active intermediates in zeolite catalysis.
