摘要

Lanthanum-doped Pd/γ-Al₂O₃ and Pd/γ-Al₂O₃ membranes were prepared by sol-gel methods. The thermal stability of the unsupported Pd/γ-Al₂O₃ and La/Pd/γ-Al₂O₃ membranes was investigated with BET (including average pore size, pore volume and BET surface area), XRD, and DTA techniques. The average pore size of the Pd/γ-Al₂O₃ membranes increased sharply after sintering at temperatures higher than 1000°C. Addition of 3 mol% lanthanum can raise the temperature of the γ-Al₂O₃ toα-Al₂O₃ phase transformation significantly. This improves the thermal stability of the Pd/γ-Al₂O₃ catalytic membranes.
