Abstract
An electrocatalyst including a substrate and CoxNiyFe2O4 nanoparticles, where x+y=1. The CoxNiyFe2O4 nanoparticles are doped with 0.01 weight percentage (wt. %) to 1.0 wt. % selenium (Se), based on the total weight of the CoxNiyFe2O4 nanoparticles. Further, the CoxNiyFe2O4 nanoparticles have a polygonal shape, and the CoxNiyFe2O4 nanoparticles are dispersed on the substrate to form the electrocatalyst.
