In this study, a straightforward solution-based deposition method followed by calcination is used to create porous bimetallic transition metal nanoarrays that integrate ruthenium from metal-organic framework-covered three-dimensional platforms, such as carbon cloth.. The oxygen reduction reaction half-wave potential of 0.875 V vs. reversible hydrogen electrode and can achieve a current density of 10 mA cm-2 at low overpotentials of 220 and 50 mV for the oxygen and hydrogen evolution reactions, respectively, and the needed cell voltage for total water splitting is just 1.49 V at a current density of 10 mA cm−2. The fabricated electrolyzer coupling splits seawater at relatively low cell voltages of 1.54 V.
