چکیده مقاله:
Electrochemical water-splitting is an ideal strategy to produce the promising substitutable energy source, hydrogen (H2). However, the sluggish kinetics of electrochemical oxygen evolution reaction (OER) and the prohibitive cost, low reserves and easy oxidation of noble metal-based electrocatalysts force researchers to explore efficient and low-cost electrocatalysts. Bimetal nanostructred materials are proved to have enhanced OER catalytic performances [1-2]. Metal-organic frameworks (MOFs), which have high specific surface area, tunable ordered porous structure and abundant intrinsic molecular metal sites, have been regarded as ideal catalyst candidates. However, their low conductivities and poor stabilities greatly hinder their wide application as electrochemical catalysts. Therefore, many efforts have been made to increase the conductivities of these materials. Bimetallic metal-organic frameworks OER electrocatalysts, especially Ni/Co-based electrocatalysts, have been proved to have enhanced OER catalytic performances [3].
In this study, a series of bimetallic Ni/Co-MOFs with different molar ratio were prepared by a fasil solvothermal method. Afterwards the OER electrocatalytic performances of Ni/Co-MOFs modified glassy carbon electrodes were investigated in 1 M KOH.
