Article: Study on preparation and technology of nanoporous platinum based metal materials by dealloying method Journal: International Journal of Nanotechnology (IJNT) 2022 Vol.19 No.6/7/8/9/10/11 pp.623 - 638 Abstract: Nanoporous metal materials have nanoscale pores and ligaments, which have the characteristics and excellent properties of both nanoporous materials and metal materials. Therefore, it has great application value in optics, chemistry, physics and so on. Compared with single metal catalyst, NP-PtRu alloy shows excellent activity for ammonia borane hydrolysis at room temperature. With the advantages of simple preparation, excellent catalytic activity and stable structure, the prepared NP-PtRu alloy has great potential application value as a catalyst in ammonia borane hydrolysis. In this paper, a series of nanoporous PtRuAl alloys with different components were prepared by dealloying method, in which the active component Al was selectively corroded in acidic solution. The morphology and composition of the prepared nanoporous PtRu alloy were characterised, and the activity of the samples was tested. The research shows that the nanoporous materials prepared by dealloying method have the advantages of controllable components, uniform structure and high yield.
