Facile synthesis of Pd–Mn3O4/C as high-efficient electrocatalyst for oxygen evolution reaction

Abstract

Herein, we report the use of carbon black as conducting scaffold to support highly-active Pd and Mn₃O₄ nanoparticles, and demonstrate their enhanced electroactivity for oxygen evolution reaction (OER). Benefiting from the synergistic effect, the as-prepared Pd–Mn₃O₄/carbon black catalyst showed substantially higher OER activity and stability than the Pd–Mn₃O₄ and Pd/C catalysts.
