Abstract

The oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) are importantprocesses for various energy devices, including polymer electrolyte fuel cells, rechargeablemetal–air batteries, and water electrolyzers. We herein report the preparation of a rare metal-free and highly efficient ORR/OER electrocatalyst by calcination of a mixture of blood meal andascidian-derived cellulose nanofibers. The obtained carbon alloys showed high ORR/OERperformances and proved to be promising electrocatalysts. The carbon alloys synthesizedentirely from biomass resources not only lead to a new electrocatalyst fabrication processbut also contribute to CO2 reduction and the realization of a good life-cycle assessment valuein fabrication of a sustainable energy device.
