a LSV polarization curve in 1 M KOH for overall water splitting; b the stability test performed at a constant voltage of 1.57 V; c photo of a water-splitting device driven by a solar cell (ca. 1.57 V); d photo of the evolution of H2 and O2. Co-Mo-N-2-600-2h was used as the cathode, and NiFe-LDH was used as the anode.
