Abstract:Oxygen reduction reaction (ORR) and oxygen evolution
reaction (OER)
are two important reactions in clean energy conversion devices. It
is necessary to develop nonprecious metal-based bifunctional catalysts
for ORR and OER. In this work, a multimetal bifunctional catalyst,
nanoparticles of trimetallic CoFeZn supported on N-doped carbon (CoFeZn/NC),
is prepared by one-step carbonizing the mixture of M-ZIFs (M = Fe,
Co, and Zn), carbon black, and melamine. CoFeZn/NC has a more mesoporous
structure and a higher sp… Show more
