    Abstract:

    Transition metal-modified microporous zeolitic materials (silicate- and phosphate-based) are attractive catalysts due to their hydrothermal stability and high catalytic activity and selectivity. Metal-modified mesoporous materials with larger pore openings have been developed for catalytic processes where larger molecules are involved. The inclusion of nanosized particles of zeolitic microporous materials with larger external surface areas and high surface activity into mesoporous matrices, i.e. the preparation of microporous/mesoporous composites, substantially enhances the catalytic activity of mesoporous materials. The important feature of nanoporous solids based on a various metal oxides is also their ability to form thin films with nanometer-scale thickness. Examples of successful preparation and/or functionalisation of new nanoporous solids encompass microporous and mesoporous silicates (MnS-1, MnMCM-41, MnTUD-1), microporous and mesoporous aluminophosphates (FeAPO-36, FeHMA), microporous/mesoporous silicate composites ((Ti,Al)-Beta/MCM-41, (Ti,Al)-Beta/MCM-48, Ti-Beta/SBA-15) as well as cubic mesoporous aluminophosphate thin films. Studies of structure-property relations of new solids have included X-ray diffraction, spectroscopic (XAS, NMR) and electron microscopy characterisation techniques.
