a, b Cyclic voltammetry (CV) plots of B-Os aerogels with varying scan rates from 40 to 160 mV s−1 and Cdl measurement of B-Os aerogels, Os NPs and Pt/C in 1.0 M KOH solution. c TOF values of B-Os aerogels, Os NPs and Pt/C in 1.0 M KOH, 0.5 M H2SO4 and 1.0 M PBS solutions, respectively. d, e iR-corrected polarization curves and corresponding overpotential changes at 10 mA cm−2 of B-Os aerogels, Os NPs and Pt/C were recorded before and after 5000 CV potential cycles in 1.0 M KOH solution. f iR-corrected polarization curves of B-Os aerogels were recorded before and after 5000 CV potential cycles in 0.5 M H2SO4 and 1.0 M PBS solutions, respectively. g The chronopotentiometry of B-Os aerogels, Os NPs and Pt/C in 1.0 M KOH, 0.5 M H2SO4 and 1.0 M PBS solutions, respectively.
