Abstract
A novel photocatalytic deposition method for the preparation of a thin tubular palladium membrane is presented in this paper. The membrane is prepared on a porous asymmetric TiO2 support by photocatalytic reaction of palladium ion, followed by electroless plating. Gas permeation results show that the membrane exhibits increased hydrogen permeance with the increase of temperature. The hydrogen permeance and selectivity to nitrogen at 773 K are about 1.43×10(-6) mol m(-2) s(-1) Pa(-1) and 17, respectively, when the pressure in the feed side is 0.1MPa. The activation energy of hydrogen permeation is 11.06 kJ/mol at the temperature range of 573-773 K.
