Outline of Final Research Achievements

This project was based on the control of the location of catalytic active sites derived from heteroatoms in zeolite framework, and accurate evaluation of the location of the active sites, and clarification of the relationship between the location of catalytic active site and the catalytic performance in the MTO reaction. The principal investigator, Dr. Yokoi, developed a method for controlling the location of catalytic active sites derived from heteroatoms in zeolite framework, and evaluate the catalytic performance. The international collaborator, Prof. Ute Kolb, focused on the development of the evaluation method of catalytic active sites based on advanced transmission electron microscopic technique. Other Japanese colleagues, Dr. Tsunoji and Dr. Moteki, investigated on the type of zeolites and active species. Dr. Nakasaka designed the location of active sites in zeolite framework in terms of chemical engineering including diffusion process.
