Abstract

Herein, we have demonstrated Lewis acid Fe(III)-assisted hydroxylation of ZIF-67 to form Fe_xCo-layered double hydroxide (LDH) nanosheets. The catalyst Fe_0.4Co-LDH produced an excellent water oxidation activity to reach a current density of 20 mA cm⁻² at only 190 mV overpotential, superior to that of hydrothermally synthesized LDH with a similar composition.
