Phenol decomposition using Mn+/TiO2 photocatalysts supported by the sol-gel technique on glass fibres

Li‐doped nanosized TiO2 powder with enhanced photocalatylic acivity under sunlight irradiation

“…For example, Khan et al [17] have shown efficient photochemical water splitting by a chemically modified TiO 2 , in which carbon substitutes some of the lattice oxygen. Brezová et al [22] reported that the presence of metals, such as Li + , Zn 2+ , Cd 2+ , Ce 3+ , Mn 2+ and Fe 3+ , may significantly affect the photoactivity of TiO 2 prepared by sol-gel technique. These authors showed that doping TiO 2 with Li + , Zn 2+ or Cd 2+ improves the photoactivity of TiO 2 with the maximum effect of Li + in the case of phenol photodecomposition.…”

Effect of Cobalt Doping on the Phase Transformation of TiO<SUB>2</SUB> Nanoparticles

“…The incorporation of metal ions into the titania crystal lattice can significantly extend the absorption edge into the visible region. [21][22][23][24][25][26][27] However, the photoactivity of the doped TiO 2 photocatalysts depends substantially on the nature of the dopant ion and its concentration, in addition to the method of preparation and the thermal and reductive treatments involved in the synthesis. [21][22][23] Recently, Co-doped TiO 2 films have also attracted considerable attention due to their potential application as diluted magnetic semiconductors (DMS).…”

Studies on Simulated Ageing of Paper by Photochemical Degradation

“…Titanium dioxide is a semiconductor photocatalyst for organic compounds degradation [11][12][13][14][15][16][17][18][19] . When TiO 2 absorbs light having energy ≥ 3,2 eV (band gap energy [13][14], electrons and holes are formed in the conduction and valence band respectively (ecb and h + vb ) 11 -16 .…”
