Title
Using of modified silicates and aluminosilicates as nanoreactors for organic reactions II
Code
SP2019/30
Summary
The proposed project continues on the previous project (SP2018 / 91) in investigating the hypothesis that catalytic activity as such contributes not only to the presence of active catalytic sites, whether on the surface or in the pores of the catalyst, but also to the overall environment of pores and other geometric cavities that the silicate structures offer, and can be considered as sui generis nanoreactors.
The aim of the project is to identify and characterize such sites in natural and artificially prepared layered silicates using AFM, TEM, XRD, SEM, XPS and theoretical calculations, characterizing chemical connections that lead to their catalytic / nanoreactor activity. If necessary, detected areas specifically modify to be suitable for the selected nanoreactors organic reactions. Part of the objectives of the proposed project is to prove the functionality of such nanoreactors at least one other type of reaction beyond the previous projects (SP2018 / 91, SP2017 / 69), using experiments investigating catalytic activity and product distribution (by means of instrumentation LC / MS, GC / MS, NMR , IR and Raman spectrometry), and to report these results in the form of publications, conference papers at conferences, or short reports to specialist journals.
Under this project, cooperate with the prof. Ing. Jiří Čejka, DrSc. (CUCAM Centre, Charles University) and RNDr. Alexandr Martaus, Ph. D. (IET, VŠB-TUO). Further, cooperate with Ing. Jan Nedoma, Ph. D. (Department of Telecommunications Engineering, FEI, VŠB-TUO), Ing. Vladimír Foldyna (Institute of Geonics of the CAS), and prof. Ing. Petr Martincem, CSc. (Institute of Geonics of the CAS).
