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

Reduction of nitroaromatics on cadmium sulfide: further probing the electrochemical model of semiconductor photocatalysis

Autor: Rossano Amadelli, Alexander B. Velichenko, O. Shmychkova, Luca Samiolo

Publikováno v: Journal of Solid State Electrochemistry. 25:85-92

The photoreduction of nitroarene compounds is a typical multielectron process that is examined here at cadmium sulfide electrodes and particle suspensions. Electrochemistry in the dark and photoluminescence indicate that reduction is mediated by surf

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,

N-doped TiO2 powders were prepared by two different sol-gel methods. Samples were characterised by X-ray diffraction (XRD), BET specific surface area measurements (SSA), scanning electron microscopy (SEM), diffuse reflectance spectroscopy (DRS), X-ra

Using the EPR spin trapping technique, we prove that simultaneous reactions take place in illuminated suspensions of TiO2 in aqueous carbonate solutions (pH approximate to 7). The adsorbed HCO3- is reduced to formate as directly made evident by the d
