Abstract

Abstract: A method of hydrothermal synthesis coupled with activation etching was employed to synthesize zinc oxide (ZnO) particles with six distinct morphologies: rod, tube, screw, rod-flower, tube-flower, and screw-flower. The controlled synthesis of ZnO from dispersed rods to aggregated rod-flower clusters was achieved by adjusting the parameters of the hydrothermal reaction. Moreover, by exploiting the differences in the stability of various crystal faces, a customized post-etching method was used to effectively control the morphological evolution of ZnO from rod-like structure to tubular and screw-like structures. The results of photoelectrochemical test indicated that the distinct morphology of ZnO played a significant role in its photoelectrochemical property. These findings offer valuable insights into the synthesis of ZnO with specific morphologies to tailoring its properties for particular application.
