| الوصف: | Urea/1-ethyl-3-methylimidazolium chloride (urea-EMIC) was developed to electrodeposit Cu from Cu2O at room temperature. Density, viscosity and conductivity of this urea-EMIC system were obtained. The cyclic voltammograms illustrated that the electroreduction of copper ion (Cu(I) ion) involves a quasi-reversible and one-step single electron transfer process. Chronoamperometric studies showed that the copper electrodeposition proceeds a three-dimensional (3D) progressive model. With an increase in temperature, on voltammograms the onset potentials for copper ion reduction shifted anodically and the diffusion coefficient determined using chronoamperometry increased from 5.40 × 10−11 m2 s−1 at 333 K to 1.02 × 10−10 m2 s−1 at 363 K. Also, potentiostatic electrolysis was conducted on tungsten substrates at − 0.65 V (vs. Ag) and 363 K. Then spherical metallic copper electrodeposits were obtained. |
