Caption

OER catalytic activity of W-Co3O4 in alkaline environment. (a-c) iR-corrected polarization curves, overpotentials required for j = 10 mA cm-2, and the corresponding Tafel plots of W-Co3O4, Co3O4 and IrO2. (d) Current densities in CV plotted against scan rates for W-Co3O4 and Co3O4 (the linear slope is twice Cdl). (e) iR-corrected polarization curves normalized by ECSA of W-Co3O4 and Co3O4. (f) TOFs at 1.58 V normalized by mass or ECSA of W-Co3O4 and Co3O4. (g) η10 comparisons of W-Co3O4 and state-of-the-art cobalt oxide-based OER electrocatalysts.
