A Self-Healing Platinum Catalyst for Methanol Oxidation Reaction
Chinese Academy of Sciences · University of Chinese Academy of Sciences
Abstract
Self-healing catalysts are crucial for achieving the catalytic stability of the electrochemical reactions. However, designing self-healing structures is essential for optimal catalysts without relying on external interventions, but it remains extremely challenging. Here a self-healing platinum catalyst composed of oxygen vacancy (VO) and active oxygen (GDY/VO-PtOx Cc) is designed to realize different methanol oxidation routes and high-performance alkaline methanol oxidation reactions (MOR). The resulting catalyst displays excellent mass activity of 8.8 A mgPt–1 for MOR, 1 order of magnitude higher than the commercial Pt/C. The catalyst also demonstrates robust durability with no current density loss even after…
