Fullerene Network‐Buffered Platinum Nanoparticles Toward Efficient and Stable Electrochemical Ammonia Oxidation Reaction for Hydrogen Production
Abstract
Abstract Green ammonia is a promising hydrogen carrier due to its well‐established production, storage, and transportation infrastructure. Moreover, hydrogen production via electrochemical ammonia oxidation reaction (AOR) requires a significantly lower theoretical potential than water electrolysis. However, the sluggish kinetics and poor stability of AOR hinder the industrial application of ammonia electrolysis. Herein, we report the construction of two‐dimensional covalently bonded fullerene polymeric network (PNW‐C 60 ) supported platinum nanoparticles (Pt NPs) as a highly active and stable AOR electrocatalyst. The unique electron buffering effect of PNW‐C 60 enhances the desorption of nitrogen‐containing species and prevents their poisoning on the Pt NPs surface. Consequently, the as‐obtained PNW‐C 60 ‐buffered Pt NPs exhibits a high mass activity of 118 A g Pt −1 as well as good stability, outperforming commercial Pt/C and graphene‐supported Pt NPs AOR catalysts.
