| Different nanostructured catalytic membranes have been prepared by platinum deposition (evaporation-crystallisation and ionic impregnation) within the porous framework of different tubular porous supports of a few nanometer pore size. The aim of the work is to investigate the influence of preparation methods and the influence of the type of support on the properties of the obtained catalytic membranes. Some parameters of the preparation procedure, controlling the deposition performance, have been explored. Various types of supports made of different types of oxides and carbon with different layer distribution and pore diameters have been investigated. The catalytic membranes have then been characterised by hydrodynamic measurements as well as by electron microscopy. An attempt of correlation between the platinum distribution within the thickness of the membrane wall and the preparation parameters and support material was carried out. |
