| description: | The aim of the project is the synthesis and the NMR characterization of micro- and mesoporous materials, which are considered as a candidate for the preparation of the new catalysts. These new materials usually pose challenges for the NMR characterization and drive the invention of new techniques and solutions. Theoretical calculations have shown, that three-valent metals in zeolite lattice, being in fourcoordinated sites, tend to be close to each other, minimizing the total lattice energy. The formed paired sites have very much different chemical and physical properties from the isolated metal sites. Our aim is to study these paired sites in the presence of two types of metals - aluminum and boron. Our main interest is the interaction of these metal sites mediated by the zeolite framework. We will study the substitution of these metals into the zeolite framework. The process of demetallisation is also one of the main interests. This project will be carried out in cooperation with the Institute of Catalysis and Surface Chemistry, Krakow, Poland. The present project will be the continuation of the previous two-year project. During the previous project we have, amongst other results, identified the two metals - aluminum and boron, with which we are going to work further. The group, headed by Dr. Miroslaw Derewinski, will be responsible for the primary synthesis of the materials. During the first year of the project all materials will be synthesized in Krakow and further characterized in both cooperating institutions. During the second year the postsynthesis treatment will be done and its impact on the properties and structure will be determined. If possible, we plan to engage in the project one student, starting from the second half of the year. |
