This paper presents a study of the growth of nanoporous anatase and rutile phases of titanium dioxide (TiO2) subjected to electrochemical anodization at room temperature without post-thermal treatment, using sulfuric acid as the electrolyte. Effects of the applied voltage on the morphological, struc...
