Abstract
An innovative electrochemical route is proposed to deposit nanocrystalline ZnO films. The approach is based on the electrochemical reduction of O 2 in a solution of zinc bis(trifluoromethanesulfonyl)imide salt in 1-butyl-1-methylpyrrolidinium bis(trifluoromethanesulfonyl)imide room temperature ionic liquid. The mechanisms involved in the deposition process are analyzed by cyclic voltammetry, pointing out that the ZnO formation occurs from the chemical reaction between the Zn 2+ and O 2 - generated from the O 2 reduction. Homogenous films constituted of primary ZnO nanocrystals (15–25 nm) assembled in close-packed desert rose-like and open-packed round-top shape agglomerates are obtained at 100 and 150 °C, respectively. The differences with respect to the electrochemical routes based on aqueous and organic media are discussed.
