Abstract

Gold decorated titanate nanowires and nanotubes were investigated by XPS, XRD and HRTEM. XPS and UVVis diffuse reflectance results suggested that a certain part of gold underwent an ion exchange process. Higher gold loadings lead to the formation of nanosized-dispersed particles complexed to oxygen vacancies, with a diameter distribution of 1.5-10 nm. Gold additives catalyzed the transformation of the tube structure to anatase. Gold, however, stabilized the wire-like structure up to 873 K.
