An inorganic membrane with permeability for H2 higher than palladium and with over 99.9% selectivity over larger species like CO, CO2 and CH4 was prepared by the deposition of a thin,20 nm SiO2 layer on a specially designed alumina support.The alumina support was obtained by the deposition of boehmite sols of controlled size on top of a porous substrate, so as to create a graded structure with increasingly small pore sizes.
