It is known that metal doping to silica by sol-gel method, such as nickel and cobalt, can change the membrane performance, for example, hydrothermal stability of amorphous silica and hydrogen separation performance.In this work, sol-gel method was applied for the preparation of palladium doped silica membranes for hydrogen separation.The membrane stability (thermal and hydrothermal) and hydrogen separation performance was evaluated by measuring the time and temperature dependency of gas permeances (N2, H2, He,) at 500℃.
