It is crucial to develop low cost, highly efficient catalysts for oxygen evolution and methanol oxidation to replace precious metal catalysts. Herein, a novel strategy for preparation of exfoliated carbon nano-structures (CNS)/metal layered double hydroxide (LDH) nanocomposites is developed via a facile electrochemical deposition. The as-prepared NiFe-LDH/CNS nanocomposite has excellent electrocatalytic activity with respect to the oxygen evolution reaction for which an overpotential of 236 mV is achieved to obtain a current density of 10 mA cm(-2) on a glassy carbon electrode. Furthermore, the as-prepared NiFe-LDH/CNS and NiCo LDH/CNS nanocomposites also exhibit excellent electrocatalytic activity with respect to methanol oxidation in alkaline electrolyte and thus have multifunctional catalytic activities.
