A Low‐Cost, Durable Bifunctional Electrocatalyst Containing Atomic Co and Pt Species for Flow Alkali‐Al/Acid Hybrid Fuel Cell and Zn–Air Battery (Adv. Funct. Mater. 47/2023).

In an article published in Advanced Functional Materials, researchers Zhenhai Wen, Cheng‐Yan Xu, and their team introduce a low-cost and durable catalyst called Pt@CoN4‐G. This catalyst contains atomic Co and Pt species encapsulated in nitrogen-doped graphene and demonstrates excellent performance in both the hydrogen evolution reaction and the oxygen reduction reaction. The catalyst shows promise for use in flow alkali‐Al/acid hybrid fuel cells and Zn–air batteries. The researchers attribute the catalyst's success to the strong metal support interactions between the Pt species and the CoN4‐G support, as well as the synergistic cooperation of multiple active sites.
