Abstract
- Mixed oxides were detected over Cu-Zn while only Cu2O is detected over Cu-Ni surface.
- Mixed oxides/hydroxides were detected on the surface of Cu-Ni-Zn.
- Although ZnS is a wide bandgap semiconductor, it enhances the ionic conduction.
- Both XPS and XRD analyses confirm the absence of any copper sulphide in case of Cu-Ni-Zn.
- Polysulfide (S8) is formed on the surface of Cu-Ni and Cu-Zn.
