Abstract

Pd-Ag alloy membranes (0.4 μm) have been prepared on porous TiO₂/Al₂O₃ support via a photocatalytic co-deposition technique. Using this technique the membrane composition can be precisely controlled and the alloying of Pd-Ag carried out more easily. X-ray diffraction and scanning electronic microscopy analysis of the Pd-Ag composite membranes indicated that the metal existed in the form of alloy and membrane surface appeared homogeneous. A gas permeation experiment was conducted under temperature of 693 K and pressure of 0.01-0.06 MPa. Hydrogen permeance and selectivity of hydrogen/nitrogen (H₂/N₂) were 1 × 10^{- 5} mol m^{- 2} s^{- 1} Pa^{- 1} and 7.1-7.4, respectively.
