Alloys with Pt-skin or Pt-rich surface for electrocatalysis

Publication date: June 2018Source: Current Opinion in Chemical Engineering, Volume 20Author(s): Jing Li, Li Li, Min Jie Wang, Jianchuan Wang, Zidong WeiThe Pt-based alloys with Pt-skin or Pt-rich surface own significant structural advantages for a range of electrocatalytic reactions. Herein, we give a minireview for such catalysts, which covers a brief background introduction, the mechanisms for the activity enhancements derived from the special Pt-skin structures, the very recent advances on the preparation routes and applications of the catalysts in various electrochemical reactions, and a future perspective. Indeed the Pt-skin structured catalysts have shown great promising which in the future, may provide more opportunities for enhancing electrocatalytic performance at the molecular level.Graphical abstract
