a Polarization curves of the electrolytic cell with MoS2/NiFe LDH | MoNiFe coupled electrodes and the reference cell with Pt/C | RuO2 coupled electrodes for overall water splitting. b Chronopotentiometry curves at the current density of 100 mA/cm2 of the electrolytic cell with MoS2/NiFe LDH | MoNiFe coupled electrodes and the reference cell with Pt/C | RuO2 coupled electrodes. c The comparison of overall water splitting performance at the current density of 100 mA/cm2 for MoS2/NiFe LDH | MoNiFe and other noble-metal-free electrocatalysts in recently reported literature, such as MnCo-CH@NiFe-OH (1.69 V)61, NiFe-LDH/Ni(OH)2 (1.81 V)62, NiCoFe-O@NF (1.7 V)63, NiP2/NiSe2 (1.8 V)64, Ni2P-Fe2P/NF (1.68 V)65, NiFeP-CNT@NiCo/CP (1.92 V)66, FeCo/Co2P@NPCF (1.98 V)67, Co-NC/CP (1.86 V)68 and CoP NFs (1.92 V)69.
