The nanostructural design of zinc oxide (ZnO) has been of great interest as it can effectively affect its photoelectric conversion efficiency, photocatalytic activity, electrochemical activity, and other properties. In this work, we employed an anodic aluminum oxide (AAO) template-guided approach. The structural design and replication of the AAO template enabled the controlled growth of ZnO nanostructures with precise porous morphology. As a result, highly ordered ZnO nanopore arrays were prepared with tunable pore size and height. This unique array of ZnO nanopores may have potential applications in the fields of photovoltaic conversion, gas sensing, and water decomposition. In addition, the present synthesis strategy also has the potential for precise structural design of other metal and oxide materials.

Keywords: AAO; nanostructural design; ZnO; nanopore arrays; controlled growth
