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 benzyl alcohol and cyclohexene were used to test oxidation selectivity and 4-nitro-benzaldehyde to assess selective jordanpaintsafrica.com by: Jul 15,  · Simultaneous photoreduction of U(VI) and photooxidation of As(III) was firstly achieved over the g-C 3 N 4 /TiO Photoreduction of U(VI) and photooxidation of As(III) were confirmed by XPS analysis in jordanpaintsafrica.com by: Titanium dioxide (TiO{sub 2}) colloids prepared from titanium chloride (TiCl{sub 4}) were used as photocatalysts in the experiments. Cysteine was selected as the model derivative for the surface modification of the TiO{sub 2} nanoparticles. Testing of TiO{sub 2} photocatalysts conducted in the absence of organic compounds demonstrated that adsorption of lead ions occurred in the system with Author: R.W. Peters, J.M. Wu, N. Meshkov, M.C.

VERNON ASD Owes K. ASH From the Department of Chemistry, Brigham Young University, Provo, Utah (Received for publication, February 15, ). Photooxidation and photoreduction reaction rates on nanoparticulate TiO 2 have been studied using a series of silica coated samples prepared from the same parent material—a high area rutile. Oxidation of propanol was measured by GC analysis of acetone jordanpaintsafrica.com by: The photoredox ability of the TiO2 {}, {}, and {} surfaces is investigated by examining the trapping energies, trapping sites, and relative oxidation and reduction potentials of simulated photogenerated holes and electrons in the form of more realistic polaronic states on the basis of density functional electronic structure jordanpaintsafrica.com by: Abstract— Hydrogen transfer from tertiary amines to nitroaromatics is photocatalysed by SnIV and GeIV complexes of tetraphenylporphyrin. There are two. Our results enable us to re-estimate their relative photooxidation ({} > {} > {}) and photoreduction ({} > {} > {}) activities.
