Lead dioxide electrodes for high potential anodic processes

Autor: A. B. VELICHENKO, ROSSANO AMADELLI

Publikováno v: Journal of the Serbian Chemical Society, Vol 66, Iss 11-12, Pp 835-845 (2001)

Doping of PbO2 by cations (Fe3+, Co2+ and Ni2+), by F- and by cations and F- simultaneously is discussed as a way of improving the stability and electrochemical activity in processes occurring at high potentials. Doping allows the control of the amou

Comparative visible-light driven selective oxidation to aldehydes of phenylmethanol (benzyl alcohol) and 4-pyridinylmethanol (4-pyridinecarbinol) on N-TiO2 and some commercial TiO2 samples

Autor: Andrea Maldotti, Luca Samiolo, Alessandra Molinari, Rossano Amadelli

Visible light (λ > 420 nm) selective photooxidation of phenylmethanol and 4-pyridinylmethanol in CH3CN to the corresponding aldehydes on N-TiO2 is compared with homemade undoped TiO2 (U-TiO2) and commercial undoped anatase specimens (such as PC105,

Selective Photooxidation and Photoreduction Processes at 𝐓𝐢𝐨𝟐 Surface-Modified by Grafted Vanadyl

Autor: Rossano Amadelli, Luca Samiolo, Andrea Maldotti, Alessandra Molinari, Delia Gazzoli

Publikováno v: International Journal of Photoenergy, Vol 2011 (2011)

Titanium dioxide was surface-modified by grafting vanadyl species using vanadyl triisopropoxide as a precursor. The resulting material, (VOx)n/TiO2, was characterized by Raman spectroscopy and photoelectrochemical methods. Photocatalytic oxidation of

Preparation, Characterisation, and Photocatalytic Behaviour of Co-TiO2 with Visible Light Response

Autor: Rossano Amadelli, Luca Samiolo, Andrea Maldotti, Alessandra Molinari, Mario Valigi, Delia Gazzoli

Publikováno v: International Journal of Photoenergy, Vol 2008 (2008)

The preparation of cobalt-modified TiO2 (Co-TiO2) was carried out by the incipient impregnation method starting from commercial TiO2 (Degussa, P-25) and cobalt acetate. XPS data show that cobalt is incorporated as divalent ion, and it is likely prese

Electrodeposition of composite PbO2–TiO2 materials from colloidal methanesulfonate electrolytes

Autor: V. Knysh, O. Shmychkova, Tatiana Luk'yanenko, Rossano Amadelli, Alexander B. Velichenko

Publikováno v: Journal of Solid State Electrochemistry. 21:537-544

The influence of particles of colloidal titanium dioxide on the morphology and structure of lead dioxide electrodeposits has been investigated. The presence of colloidal TiO2 particles (at levels of up to 1 g dm−3) in the electrolyte leads to an in

Electrodeposition of Ni2+-doped PbO2 and physicochemical properties of the coating

Autor: Tatiana Luk'yanenko, Alexander B. Velichenko, Rossano Amadelli, O. Shmychkova

Publikováno v: Journal of Electroanalytical Chemistry. 774:88-94

The kinetics of PbO2 electrodeposition from nitrate electrolytes containing nickel ions, and the influence of deposition conditions on the physicochemical properties of obtained materials, have been investigated. This study reveals that the mechanism
