Synthesis and photocatalytic oxidation of different organic dyes by using Mn2O3/TiO2 solid solution and visible light

Synthesis of sulphur doped bismuth selenide photocatalysts by the solvothermal method and their photocatalytic activities under visible-light irradiation

“…The first approach involves doping of various nonmetals into photocatalysts with wide band-gap energies to intercalate localized donor levels in the forbidden band [1,4]. The second approach is the regulation of band-gap energies by making a compound of two different semiconductors with wide and narrow band-gaps [2,3,5,[11][12][13]. The third approach is the building up of a valence band in a more negative position [14][15][16][17][18].…”

Synthesis of TiO2/WO3/MnO2 Composites and High-Throughput Screening for Their Photoelectrical Properties

“…Tanmay et al prepared Mn 2 O 3 doped TiO 2 using TiO 2 and KMnO 4 , which exhibited photocatalytic activity 3-5 times higher than P25 for oxidation of RB. 32 There were no distinct photoelectric responses at the MnO 2 corner that might attribute to the large amount of Mn 2 O 3 of the composite material system in our experiment. Thus, Mn 2 O 3 might have a great significance in promoting the separation of electron and hole in TiO 2 when the amount of Mn 2 O 3 is less.…”

Synthesis of spherical mesoporous titania modified iron-niobate nanoclusters for photocatalytic reduction of 4-nitrophenol

“…Therefore, many research scientists are now-a-days involved in the research work on the photocatalytic activity of TiO 2 doped with different metal ions such as Ag [29], Au [30], Mn [31], Fe [32,33], Co [34], Ni [35,36], Cu [37,38], and Pd [39] etc. Recently, non-metals such as nitrogen doped La 2 Ti 2 O 7 [40,41], nitrate and nitrite doped TiO 2 were shown to be good photocatalysts [42].…”
