Abstract
The coupling of zinc oxide tetrapods (t‐ZnO) with anatase TiO~2~ in the form of CVD coatings on ZnO nanotetrapods was investigated. t‐ZnO/TiO~2~ core‐shell structures, consisting of uniformly and completely TiO~2~ covered ZnO nanotetrapods, were characterized by scanning electron microscopy, X‐ray diffraction and UV‐Vis spectra. Photocatalytic activity, determined by degradation of a sodium methyl red solution, was found to be comparable to pure t‐ZnO, while improved separation easiness was verified that makes the presented powders promising for wastewater treatment.
