Electrosynthesis of zinc oxide has been performed in track etched polymer membranes to yield nanorods of defined diameter and controlled length. The electrodeposition process involves two steps: (i) electroreduction of either hydrogen peroxide or nitrate ions to alter the local pH within the pores and (ii) precipitation of the metal oxide within the pores. Synthesis at 22°C via the reduction of hydrogen peroxide yielded polycrystalline zinc oxide nanorods. When deposition was performed at 90°C, using the reduction of nitrate to control the local pH, zinc oxide nanorods which displayed the same growth direction along their entire length were obtained. The length of all as-grown rods increased with the integrated charge passed. The growth direction of the ZnO rods obtained at the higher temperature was unusual, being perpendicular to the (101) plane.
