a Polarization curves (current normalized by oxide BET surface area) of the as-synthesized NaxMn3O7. (The 2st LSV curve is used for comparison.) b Comparison of the normalized current densities based on BET surface area at 1.55 V versus RHE (the right y axle shows the relationship between P1 and P2 with the number of Na+ in NaxMn3O7.). c Tafel plots with the previously benchmarked IrO235 as a comparison. d Chronoamperometric curve of NaMn3O7 at 1.55 V versus RHE (The inset shows the 2nd, 10th, 25th, and 50th CV scans of NaMn3O7).
