Preparation and characterization of doped titanium dioxide printed layers

Recent advances and prospects of inkjet printing in heterogeneous catalysis

“…Surfactants such as Abesone and Triton X-100 act as dispersing agents and reduce the surface tension of metal oxide colloidal solutions. 100,101 Co-polymer macromolecules such as polyethylene glycol (PEG) are used to increase the layer uniformity and prevent cracking during the post thermal treatments. 102 They also hinder the coffee ring effect caused by the capillary flow of particles from the droplet centre to the evaporation interface.…”

Structure and catalytic performance of Zn-doped TiO2 film

“…Introducing some defects, such as doping nonmetal (Lin et al , 2017; Lee et al , 2015; Cinelli et al , 2017; Sridhar et al , 2016) or metal species (Diaz-Uribe et al , 2014; Belver et al , 2017), in the lattice of titanium dioxide is one of the effective ways to obtain better visible light response. Meanwhile, an effective method, modified TiO 2 by metal ions, proves the expansion of absorption light from ultraviolet to visible region, and reduces the recombination rate of photogenerated electrons and holes (Joung et al , 2006; Wang et al , 2014; Kralova et al , 2014; Zhuang et al , 2015) and coworkers have studied the cerium, silver and iron doped TiO 2 film. In addition, the doping could narrow band gap of TiO 2 and induce an absorption edge widening.…”

Effect of Cu on optical properties of TiO2 nanoparticles

“…To overcome this limitation, different ways have been investigated to extend its activity to visible region, making a better use of solar resource. Modification of electronic structure (doped) through insertion of non-metal ions, transition metal ions or rare earth elements has been an important alternative [6][7][8][9]. Metal transition doped has demonstrated to be an effective alternative to reduce the band gap of TiO2 because it creates impurity levels that allow the electronic transitions within the conduction band and valence band, and simultaneously reduces the recombination rate of photogenerated charges [10].…”
