Figure 7. (A) Cyclic voltammetry curves of electrodes with different Pt-Mo-based catalysts in an O2-saturated 3.5 wt.% NaCl aqueous solution at a scanning rate of 50 mV·s-1[87]. (B) Discharge profiles of Mg-air batteries using different Pt-Mo-based catalysts at a current density of 5 mA·cm-2 in a 3.5 wt.% NaCl electrolyte[87]. (C) Rotating-disk voltammograms of Mn3O4 NW/3D GN/SWCNT in O2-saturated 0.1 M KOH at a sweep rate of 10 mV·s-1 and different rotation rates[94]. (D) Discharge profile of Mg-air batteries using Mn3O4 nanowires/three-dimensional graphene/single-walled carbon nanotube (Mn3O4 NW/3D GN/SWCNT) catalysts in a mixed electrolyte of Mg(NO3)2 (2.6 M) and NaNO2 (3.6 M) with the additive of 1.0 wt.% [P6,6,6,14][Cl] ionic liquid. The inset illustration is the schematic diagram of the controllable growth of one-dimensional Mn3O4 nanowires on graphene in the microwave field[94].
