Fig. 3

a OER activities of hybrid BSCF, pure BSCF, BSCF5582, and IrO2 catalysts measured on GCE in 0.1 M KOH at 25 °C. b OER performance of hybrid BSCF with different catalyst loadings tested on nickel foam. c ICP-MS results of Ba2+ and Sr2+ ions in pristine powders and CV-activated samples. d Cl 2p XPS spectra of hybrid BSCF before and after CV activations. HRTEM images of e pure BSCF after OER (scale bar is 5 nm) and f hybrid BSCF after OER (scale bar is 2 nm). Inset figures are the corresponding FFT patters of respective crystalline structures.
