Nanocrystalline TiO2 (Anatase) Electrodes: Surface Morphology, Adsorption, and Electrochemical Properties

Abstract

Ten different nanotextured films were prepared from six commercial and four laboratory synthesized precursors. Krypton adsorption isotherms on the films and parent powders indicate the effect of sintering and agglomeration. Electrochemical characterization of the films was aimed at double‐layer charging and insertion. The relations between the film's morphology, adsorption properties, and electrochemical behavior in the accumulation regime are discussed.
