Effect of metal-doping of TiO2 nanoparticles on their photocatalytic activities toward removal of organic dyes

Photocatalytic degradation of hexavalent chromium emerging contaminant via advanced titanium dioxide nanostructures

“…Besides affecting electronhole recombination, doping metal ions into the TiO 2 lattice essentially decreases the semiconductor's band gap and therefore, the energy needed for photo-excitation, turning TiO 2 into a visiblelight responsive catalyst. Cu has extensively been studied as dopant into the TiO 2 lattice [9][10][11][12][13][14]. In most of the cases, the preparation method makes use of copper salts incorporated into the titanium alkoxide precursor solutions during the sol-gel synthesis of TiO 2 .…”

Photocatalytic Activity of Synthetic N‐doped TiO2/Reduced Graphene Oxide Crystalline Composites

“…So far, numerous researchers have designed some strategies to overcome these issues, including nonmetal doping [14], metal ion doping [15], noble metal loading [16], dye sensitization [17], and composite semiconductors [18]. Recently, efficiently modified methods are expected to be compounded with graphene, a 2D carbon sheet with a large amount of sp 2 -bonded, to increase the transfer of photoelectrons and surface adsorption of dyes through p-p interactions [19][20][21][22][23][24].…”

Visible Light Photocatalytic Degradation of Azo Dye and a Real Textile Wastewater Using Mn, Mo, La/TiO2 /AC Nanocomposite

“…Previous studies have shown that doping with metals improved the photocatalytic efficiency of TiO 2 and could be considered as a promising strategy 29 . The verified metal dopants, including Mn 30,31 , Cu, Co 32 , Ag 33 , La 34 , Sn 35 , and so on, not only reduced the rate of recombination of electron/hole, but also increased the adsorption in the visible light region 27 . Extensive studies have been carried out in terms of mono doping TiO 2 with transition metals, such as La, Ag, Mn, Co, Cu, Mo, Au, Pt, etc 34 .…”
