Noble metal/titanium dioxide nanocermets for photoelectrochemical applications

Effect of nitrogen doping on TiOxNy thin film formation at reactive high-power pulsed magnetron sputtering

“…Two basic group of dopants can be used: (i) cations of transition metals such as Fe, Ni, Cr, Mn, V, Ag, Au, which can increase absorption of visible spectra but usually suffer from thermal instability [2][3][4][5][6], and (ii) non-metal anion such as N − [7][8][9][10], C − [11], S − [12], F − [13], which shift the band-gap towards lower spectral frequencies. Among the doping elements, N was found to be most effective because (i) nitrogen has comparable ionic radius to oxygen and (ii) the p states of N contribute to bandgap narrowing by mixing with O 2p states [9,14].…”

Preparations and photocatalytic degradation of methyl orange in water on magnetically separable Bi12TiO20supported on nickel ferrite

“…Many studies have been made in the development of photocatalysts that can efficiently utilize solar or indoor light. The approaches include the modification of TiO 2 [19][20][21][22][23][24][25] and the development of new type photocatalysts, such as SrTiO 3 [26], Bi 2 GaTaO 7 [27], InTaO 4 [28]. However, the report about the photocatalyst possessing of magnetic property and visible-light activity is hardly found.…”

Degradation of bisphenol A in aqueous solution by H2O2-assisted photoelectrocatalytic oxidation

“…Many research papers have reported that noble metal surface modification could improve the reaction activity of TiO 2 catalyst [18,19]. In this study, the gold-modified under visible light illumination.…”
