text: The design and engineering of earth-abundant catalysts that are both cost-effective
and highly active for water splitting are crucial challenges in a number of energy
conversion and storage technologies. In this direction, herein we report the synthesis
of Fe3O4@NiFexOy core-shell nanoheterostructures and the characterization of their
electrocatalytic performance toward the oxygen evolution reaction (OER). Such
nanoparticles (NPs) were produced by a two-step synthesis procedure involving
the colloidal synthesis of Fe3O4 nanocubes with a defective shell and the posterior
diffusion of nickel cations within this defective shell. Fe3O4@NiFexOy NPs were
subsequently spin-coated over ITO-covered glass and their electrocatalytic activity
toward water oxidation in carbonate electrolyte was characterized. Fe3O4@NiFexOy
catalysts reached current densities above 1 mA/cm2 with a 410 mV overpotential
and Tafel slopes of 48 mV/dec, which is among the best electrocatalytic performances
reported in carbonate electrolyte.
