“…The authors [17] have previously shown that the doping with manganese ions reduced the temperature of anatase-rutile phase transition. Concentration of rutile to the anatase in powder 5% Cu/TiO 2 is negligible while in the manganese sample it was 41%.…”

Mesoporous nanosized titania films modified with Co2+, Ni2+, Mn3+, and Cu2+ ions have been produced by templated sol-gel method and characterized by optical spectroscopy, X-ray diffraction (XRD), and Brunauer, Emmett, and Teller (BET) surface area measurement. Band gap energy and the position of flat band potentials were estimated by photoelectrochemical measurements. The films doped with transition metals possessed higher photocurrent quantum yield, as well as photo- and electrochemical activity compared to undoped samples. Mn+/TiO2 (M–Co, Ni, Mn, Cu) electrodes with low dopant content demonstrate high efficiency in electrocatalytic reduction of dissolved oxygen. Polarization curves of TiO2, TiO2/Ni2+, TiO2/Co2+/3+, and TiO2/Mn3+ electrodes contain only one current wave (oxygen reduction current). It means that reaction proceeds without the formation of an intermediate product H2O2.

“…The presence of rutile phase was observed only in the samples of 5 % Cu/ТіО 2 and 5% Mn/ТіО 2 . The authors [12] previously showed that the doping with manganese ions reduced the temperature of anatase -rutile phase transition. Concentration of rutile in powder 5 % Cu/ТіО 2 was negligible while in the manganese sample it was 41 %.…”

Abstract. Fe/TiO 2 , Mn/TiO 2 , Zn/TiO 2 , Cd/TiO 2 , Ni/TiO 2 titania nanotubes were synthesized by the method of direct hydrothermal synthesis. Their properties have been investigated using X-ray phase analysis and X-ray fluorescent analysis, high-resolution transmission electron microscopy, luminescent spectroscopy and Raman scattering. It has been ascertained that the Fe/TiO 2 , Mn/TiO 2 , Zn/TiO 2 , TiO 2 titania nanotubes possess the structure of Na 2 Ti 2 O 4 (OH) 2 . The structure of Cd/TiO 2 titania, probably, is mixture of anatase and rutile phases. We have found that Fe, Mn, Zn, Cd, Ni does not form solid solution with TiO 2 , and these metals are located in interlayer space. The mechanism of nanotube formation has been briefly discussed.
