Efficient oxygen reduction by nanocomposites of heterometallic carbide and nitrogen-enriched carbon derived from the cobalt-encapsulated indium–MOF

Abstract

By one-step pyrolysis of an indium-MOF with entrapped cobalt dimers in the presence of melamine, heterometallic carbide nanoparticles (Co3InC0.75) embedded in nitrogen-enriched carbon have been prepared and found to exhibit efficient electrocatalytic activity for oxygen reduction reaction with high durability and methanol-tolerance properties.
