Substantial Electrocatalytic Oxygen Evolution Performances of Activated Carbon-Decorated Vanadium Pentoxide Nanocomposites

Figure 6

OER performances: (a) -corrected LSV curves, (b) Tafel plots, (c) CP profiles at different current densities of 10 to 100 mA/cm² of the V₂O₅ and the AC-V₂O₅ catalysts, and (d) CP OER stability of the V₂O₅ and the AC-V₂O₅ catalysts measured up to 20 h at 10 mA/cm². The gray curve in (a) was measured from commercial RuO₂ to compare our results with the well-known standard catalyst.
