Abstract

Ni-Mo alloys were electrodeposited in the deep eutectic solvent system. To obtain the information on deposit's morphology

structure and hydrogen evolution activity

scanning electron microscopy (SEM)

X-ray diffraction (XRD) and polarization curve test were used respectively. SEM images and XRD pattern showed that the prepared alloy had a nanocrystalline structure with average crystallites size of 2.2 nm. The deposit contained about 5% (mass) Mo and had a large roughness factor. Polarization curves indicated that hydrogen generation potential of Ni-Mo alloy deposited in ionic liquid had a positively shift of about 100 mV compared to Ni-Mo alloy deposited in aqueous solution and had a positive shift of about 250 mV compared to pure Ni electrode at current density of 0.1 A·cm2.
