a Magnetic hysteresis loops of CoFe2O4, Co3O4, and IrO2 powders at room temperature (300 K) and the magnified graph inset in the top left of this panel. (Here, IrO2 powder is a commercial catalyst (bulk, Premetek). Cyclic voltammetry (CV) of CoFe2O4 (b), Co3O4 (c), and IrO2 (d) catalysts at a scan rate of 10 mV/s in O2-saturated 1 M KOH with and without a constant magnetic field (10,000 Oe). e The schematic of the generation of the polarized electron under a constant magnetic field. The Tafel plots of CoFe2O4, (f) Co3O4 (g), and IrO2 (h) catalysts with and without a constant magnetic field (10,000 Oe). The error bar represents three independent tests.
