OERs (in 0.1 N KCl) of as-prepared PAW (red), various 10 day aged PAW and DI water (black) for reference. (A) LSV of as-prepared PAW, 10 day aged PAW-4-10 and DI water. (B) Statistical results of currents at 1.5 V vs Ag/AgCl of various samples. Blue: slowly frozen/quickly melted PAW-2-10; pink: quickly frozen/slowly melted PAW-3-10; orange: quickly frozen/quickly melted PAW-4-10. *, p < 0.05.
