Fabrication of the anodic metals nanorod, especially Ti (titanium) nanorod arrays (Ti‐NRAs), has attracted increasing attention in recent years. In this reported work, Ti‐NRAs were prepared by applying a constant current of 200 mA under different anodisation conditions. The field emission scanning electron microscopy results showed that the density of the Ti‐NRAs could be periodically tuned by the conditions of electrochemical anodisation. A possible formation mechanism is proposed to demonstrate the periodical tuning of the Ti‐NRAs' density by the electrochemical anodisation time. This well‐controlled synthesis approach may shed light on the fabrication of similar nanostructures of other metal materials.
