Abstract
In this study, Cu
2
S/ZnO nanorods arrays (NRAs) nanocomposite have been efficiently papered via dual methods: firstly, ZnO NRAs by a hydrothermal method, and secondly Cu
2
S nanoparticles via successive ionic layer adsorption (SILAR). Cu
2
S/ZnO photoelectrode is collected from ZnO which is presented as a fast electron transportation way because of its high mobility and Cu
2
S as good sensitized material due to its small energy gap. XRD analysis, FESEM images, EDX analysis, UV–Vis spectra and photoelectrochemical performance (PEC) of bra ZnO and Cu
2
S/ZnO were characterized. All characterizations have confirmed formed the Cu
2
S/ZnO NRAs nanocomposite. PEC measurement was strong evidence to synthesis of Cu
2
S/ZnO which exhibited the anodic photocurrent density of pure ZnO NRs (0.12 mA cm
−2
) that was lower than Cu
2
S/ZnO NRAs (0.93 mA cm
−2
) at 1.0 V vs. Ag/AgCl.
