Thin Pd-composite membrane on porous nickel support by means of sputtering and polishing method |
| 초록 |
This study shows that a highly selective Pdmembrane can be depoaited on porous metal substrate by means of sputtering followed by polishing treatment. It is impossible to remove pinholes generated on the Pd membrane surface by sputtering only. Polishing treatment was introduced to remove the pinholes. SEM and helium leak tests confirmed that the polishing treatment was very effective method in removing the pinholes. Hydrogen permeation and helium leak tests showed that our membrane has very high H2/He selectivity (>40,000) at a pressure difference of 100 kPa and 673 K. Hydrogen permeation flux increased with increasing temperature and pressure difference to 1.8 mol m-2 s-1 at 673 K and 2,000 kPa. The advanatage of our manufacturing procedures is its simplicity and reproducibility. |
