•ZnO rod arrays with different diameter sizes and orientation were synthesized.•The effect of substrates and deposition times on the morphology of ZnO films was investigated.•PL properties have been investigated at room temperature.•The photocatalytic activity of eight films was compared and analyzed.
ZnO micro/nanorod arrays were successfully grown on different substrates (such as Si/seeds, Si, glass and Zn) through chemical bath deposition (CBD) method. The substrates were found to have effect not only on the diameter size but also on the orientation of ZnO rod arrays. By further varying deposition times, different diameter sizes of ZnO rod arrays were also obtained. Photoluminescence (PL) and photocatalysis properties were studied at room temperature. The photocatalytic results showed that the photocatalytic activities of ZnO rod arrays not only depend on diameter size, but also depend on other factors (such as orientation, morphology and amount of photocatalyst). ZnO rod arrays with the smallest diameter and highest orientation exhibited the maximum photocatalytic activity.
