Photocatalytic activity of nitrogen and copper doped TiO2 nanoparticles prepared by microwave-assisted sol-gel process

Dye degradation performance, bactericidal behavior and molecular docking analysis of Cu-doped TiO2 nanoparticles

“…As a result of recombination of electron-holes, titania exhibits poor band gap emission, which optically allows for the irradiative recombination of trap states. [10][11][12][13] In general, recombination instigated by impurities and defects as well as various other aspects lead to incorporation of bulk and surface imperfections into crystals, which may occur either on the surface or in bulk. Additionally, decrease in particle size usually leads to an increase in surface recombination.…”

Solvothermal synthesis and characterisation of doped TiO 2 nanocrystals for light scattering applications

“…This sample endorses the anatase phase without other impurities like CuO/N 2 O. The broadening and shifting of the diffraction peaks after Cu doping indicates the distortion of the unit cell and thus reduced crystallite size [17]. This is because the doping ion results in several crystal planes which yield lattice deformation [18].…”

Impact of Titanium Dioxide (TiO2) Modification on Its Application to Pollution Treatment—A Review

“…As a result, the light response range was expanded. Doping non-metallic elements could increase the impurity level in the forbidden band of TiO 2 and help the band energy level keep higher than the reduction level, where the energy level of TiO 2 are overlap [71][72][73]. Asahi et al [74] first replaced a small amount of lattice oxygen in TiO 2 with non-metallic element N doping, and successfully achieved visible light catalytic activity of TiO 2 .…”
