Abstract:Herein, a quasi-parallel CoFe layer double hydroxide (CoFe LDH) nanosheet array was employed as precursor to regulate the deposition of MoO2 nanoparticles with abundant oxygen vacancies array by in-situ loading and calcination process. The asobtained CoFeOx/MoO2 nanoarray electrode showed the enhanced hydrogen evolution reaction (HER) activity, while it delivered the current densities of 10 and 1 000 mA·cm-2 at overpotential of 40 and 217 mV, respectively. Besides, the current density of 50 mA·cm-2 for CoFeOx/MoO2 electrode was maintained at an overpotential of 100 mV up to 125 h of operation.
Keywords:quasi-parallel nanosheet array  molybdenum dioxide  hydrogen evolution performance
