TiCl3/PdCl2法活化多孔陶瓷基体制备透氢Pd膜
Fabrication of hydrogen-permeable palladium membranes on porous ceramic substrate activated by TiCl3/PdCl2 method
摘要
Abstract
SnCl2 was replaced with TiCl3 as the sensitization agent, and the effects of the TiCl3/PdCl2 activation on the membrane fabrication and performance were investigated. The membrane surface and cross-section morphologies were characterized by SEM and metallographic microscope. The membrane permeability, selectivity and high-temperature stability were tested, and the influences of the TiCl3/PdCl2 and SnCl2/PdCl2 treatments on the palladium deposition were also studied. It could be concluded that the TiCl3/PdCl2 treatment successfully activated the porous ceramic surface as well and improved the membrane performances. Compared with the SnCl2/PdCl2 method, the TiCl3/PdCl2 treatment facilitated the membrane formation and the tin contamination to the membrane was avoided. The TiCl3/PdCl2 technique was an ideal alternative method to the SnCl2/PdCl2 method.关键词
