In this study, zinc oxide (ZnO) thin films were deposited on Fluorine-doped tin oxide (FTO) substrates
by electrochemical deposition (ECD) technique. The ECD was carried out at a constant
potential over a range of deposition times. The current-time response was recorded and discussed.
The crystal structure and morphologies of the films were studied using X-ray diffraction (XRD)
and scanning electron microscopy (SEM), respectively. Furthermore, photocatalytic performance of
methylene blue using ZnO was investigated at various quantity of ZnO and irradiation time. The
photocatalysis results showed the dependence of photodegradation process on the quantity of catalyst
and irradiation time. Moreover, the degradation rate constant and adsorption equilibrium constant
were calculated. Our analyses indicate that quantity of catalyst affects the degradation rate
constant and the efficiency, while the adsorption equilibrium constant does not.
