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,

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

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

In the present study we synthesize three TiO2 samples, TiO2-500, TiO2-750 and TiO2-850, by a sol–gel procedure varying the rutile and anatase content by calcination at different temperatures. Characterization by XRD, NIR-Raman, UV-Raman, BET, DR-UV

Photoexcitation of Na 4 W 10 O 32 dissolved in water leads to the formation of hydroxyl radicals. These species originate both from H 2 O oxidation and H 2 O 2 reduction. EPR-spin trapping investigation and laser flash photolysis experiments contribu

Photoexcitation of Na 4 W 10 O 32 dissolved in water produces a powerful oxidizing reagent that is able to form hydroxyl radicals from water. OH radicals formation has been demonstrated by EPR spin-trapping technique using DMPO as spin trap. The phot

Tetrabutylammonium decatungstate (WO) photocatalyzes radical alkylation reactions starting directly from alkanes. When using tert-butylcyclohexane and methylcyclohexane as the radical precursors, the addition to electrophilic alkenes (beta,beta-dialk

Proper reaction conditions have been found for the conversion of geraniol, citronellol, trans-2-penten-1-ol and 1-pentanol to the corresponding aldehydes with good chemo-selectivity (70%) by photochemical excitation of suspensions of P25-TiO(2). It i
