Cr-doped Pd metallene nanoribbon superstructures for the oxygen reduction reaction and formic acid oxidation

Abstract

Metallene is receiving continuous attention because of its unique properties in electrocatalysis. Herein, we report a new class of three-dimensional (3D) Cr-doped Pd metallene nanoribbon (PdCr MNR) assembly. The 3D PdCr MNR was about 4 or 5 atomic layers thick with high-density low-coordinated Pd sites and abundant defects. The 3D PdCr MNR/C exhibited significantly enhanced oxygen reduction reaction and formic acid oxidation reaction compared with the commercial Pt/C and Pd/C and long-term durability. This work introduces a new member in the class of the metallene family, and this novel material is a promising bifunctional electrocatalyst for practical direct methanol/formic acid fuel cell devices.
