Electrodeposition of Macroporous Zn and ZnO Films from Ionic Liquids

Nanostructured zinc films were prepared by electrodeposition onto templates of well-ordered regular arrays of PS spheres on ITO and gold coated glass substrates. The deposition was carried out from an ionic liquid (1-butyl-1-methylpyrrolidinium bis(trifluoromethanesulfonyl)imide) at room temperature in an argon filled glove box. The Zn films were oxidized to ZnO when exposed to air at elevated temperature. SEM images showed well organized nanostructures for both Zn and ZnO
