摘要

Anionic impregnation was used to depose platinum onot a porous membrane to be used in a gas-liquid contact Catalytic Membrane Reactor. this membrane was atube made of several layers, with a decreasing pore size in the radial direction to the axis. the top layer was mesoporous (pore diametr approx=5 nm), and made o titania. An amount of 5 nm of Pt crystallites were selectively deposited to this porous zone and formed branched-shape particles. their distribution in the membrane was precisely mopnitored using electron microscopopy (SEM, TEM and attached analysis methods). The membrane integrity was checked by nitrogen permeation experiments. Other characterisation techniques included XRD 9crystallite size) and N_2 adsorption (pore size distribution).
