Abstract
Nickel doped metal-organic frameworks MIL-110 catalysts were prepared by impregnation method. The as-prepared Ni/MIL-110 catalysts with different Ni content (10 wt.%, 20 wt.% and 30 wt.%) were characterized by XRD, SEM, elemental distribution analysis, N-2 adsorption-desorption and TEM. Ni/MIL-110 modified glassy carbon electrodes were employed to investigate the methanol electrooxidation reaction (MOR) in 0.1 M NaOH by cyclic voltammetry (CV) and chronoamperometry (CA). Ni/MIL-110 shows good electrocatalytic acidity toward MOR and MOR reaction is under diffusion controlled. And the catalytic rate constant is calculated to be 0.96 x 10(3)cm(3) mol(-1) s(-1) by CA analysis.
