a μs-TAS decay kinetics of BCN, BCN-FeOOH, CoOx-BCN and CoOx-BCN-FeOOH in N2. b μs-TAS decay kinetics of BCN and BCN-FeOOH under O2(H2O) conditions. c μs-TAS decay kinetics of BCN and CoOx-BCN under N2(H2O) conditions. d μs-TAS decay kinetics of CoOx-BCN-FeOOH in different atmospheres. e Plots of the relationships among the half-life time (t50%), electron transfer efficiency (ETE) and H2O2 yield of the investigated catalysts. f Electrochemical reduction curves of CN, BCN and BCN-FeOOH in the O2-saturated electrolyte (the oxidation curves of CN, BCN and CoOx-BCN are presented in the inset). Source data are provided as a Source Data file.
