摘要
多孔Pd材料在氢同位素吸附、分离和转运等领域有着广泛的用途和重要的工程应用价值,受到了广泛地关注.由于O2、H2O、CO2等杂质气体会对Pd表面产生毒化作用,导致氢在Pd表面的解离与向Pd体内的扩散速率的降低,多孔Pd表面的毒化机理研究为目前该领域研究的一个重点.着重阐述了多孔Pd材料的发展过程,总结了当前Pd表面毒化问题的研究现状.
Porous palladium material is widely used in adsorption, separation and transportation of hydrogen isotopes as well as other fields, which has important value of engineering application and given wide atten- tion. Porous palladium materials can be poisoned by impurity gases such as 02, H2 O, and C02, which lower the difusion rate of hydrogen separation on the surface of palladium toward inside of palladium. Due to the poison problem, the study of porous palladium material surface mechanism has become a key research. The development process of porous palladium material and the current research status of Pd surface poisoning problem were summarized in this paper.
