Electrochemical performance of electrocatalysts toward OER and whole-cell water splitting. a Linear sweep voltammograms (LSVs) curves measured in 1 M KOH at a scan rate of 5 mV s−1. b Tafel slope. c LSVs recorded at a scan rate of 5 mV s−1 during the OER before and after continuous polarization of the electrode in 1 M KOH for 5000 cycles. d Chronoamperometry curves recorded in 1 M KOH for 70 h. e Current density of Pt/C-1 vs. Pt/C-Ir/C for overall water splitting in 1 M KOH. 1: Fe3Co(PO4)4@rGO, 4: Fe2P2O7)@rGO, 5: (CoFe2O4)(Fe2O3)@rGO. Source data for a and ce are provided as a Source Data file
