ABSTRACT

Barium zirconate exhibits good thermo-chemical stability and proton conduction at high temperatures, but shows poor electron conductivity. Therefore, for high efficiency of hydrogen separation, a very thin and dense Pd-Barium zirconate membrane has to be coated on a porous substrate. A thin and dense Pd-Barium zirconate membrane was successfully synthesized on a porous substrate by means of dual sputtering method. The structural and chemical features of the BaZr0.85Y0.15O3 − δ membranes sputtered at 300oC and 400oC were investigated by X-ray diffractometry, and it was found that a well-crystallized membrane, Pm-3m space group of BaZrO3, was synthesized. The surface and cross-sectional morphologies of membrane were assessed by SEM (scanning electron microscopy) and TEM(transmission electron microscopy) of the surface and of cross sections. The cross sectional observation of Pd-BaZr0.85Y0.15O3 − δ membrane by dual sputtering shows that the coating is quite dense with columnar structure.
