Highly efficient Fe–Cu dual-site nanoparticles supported on black pearls 2000 (carbon black) as oxygen reduction reaction catalysts for Al–air batteries

Abstract

Acquiring cost-effective, high-performance, non-precious metal catalysts is crucial for substituting precious metal catalysts in the oxygen reduction reaction (ORR) to ensure sustainable energy conversion.

Design of Fe and Cu bimetallic integration into nitrogen-containing microporous graphene-like carbon via a hard-template-assisted strategy as an oxygen reduction catalyst for Al–air batteries

“…The robust electron transfer from Cu to Fe facilitates the alignment of the d band center with the Fermi level, thereby promoting dynamic splitting of the O–O band on the Cu surface and augmenting the dissociation activity. 2,20,25,59 It is widely recognized that enhancing electron transfer between active sites can substantially enhance the catalytic performance of the catalyst.…”

“…Aluminum–air batteries are considered one of the most promising options among metal–air batteries. 1–3 Their abundant raw materials, low cost, environmental friendliness, and high energy density have attracted numerous scientists to conduct extensive research on them. 4,5 The lack of full commercialization for aluminum–air batteries currently stems from the stability and activity of cathode electrocatalysts.…”
