Abstract
Catalytic inorganic membranes were prepared by depositing active mater ials over porous alumina tubes, using sol-gel and impregnation techniq ues. The concentration profiles of the different species in the membra ne were obtained using XPS. Also, the stability of the membranes was t ested by subjecting the samples to different thermal treatments. Diffe rent preparation methods are compared with the aim of attaining contro lled distributions of the active phases in the membrane. Finally, some reaction results are also presented.
