Abstract

Ethanol electrooxidation is crucial for fuel cells. However, a significant challenge in ethanol electrocatalysis is the breaking of the C-C bond to form CO2 at lower overpotentials. Herein, nickel nanoparticles modified deposited on zeolite was developed for electrocatalytic oxidation of ethanol in alkaline media. The nickel modified zeolite (Ni/Z) was derived by electrodeposition method on glassy carbon (GC) at 25 ℃ under an N2 gas. The composite possesses an efficient catalytic activity due to Ni nanoparticles have high catalytic activity, cost-effectiveness and durability. Moreover, the presence of the zeolite support accelerates the ethanol oxidation reaction (EOR) due to its high conductivity and surface area which increases the adsorption of ethanol and OH- species at lower potentials. Using scanning electron microscopy (SEM), the as-synthesized zeolite was studied to determine the morphology structure. Cyclic voltammetry shows that EOR onset potential and current density of (Ni/20%Z/GC) electrode is strongly shifted to negative potential (Eonset= 0.440 V) and higher current value (Ipa= 26.01 mA/cm2), respectively.
