Fig. 8. SEM images showing the surface morphology of the coatings obtained deposited in the IL with various water concentration: (a) 5 wt%, (b) 10 wt%, (c) 20 wt%, (d) 30 wt%. Electrodeposition obtained deposited were conducted under potentiostatic deposition at −0.6 V (vs. Ag) for a total capacity of 0.08 mA h cm⁻².
