TiO2 thin film growth using the MOCVD method
(ABM, ABC, ABPol, 2001-07)
Titanium oxide (TiO2) thin films were obtained using the MOCVD method. In this report we discuss the properties of a film, produced using a ordinary deposition apparatus, as a function of the deposition time, with constant ...
Surface and electronic properties of rutile TiO2 thin films coated with PbO2
(Elsevier B.V., 2020-01-01)
Binary films of semiconductors have lots of potential applications in material science. Initially, these films were based on In2O3 but, because of its high coast, alternative materials to replace it have been intensely ...
Influence of laser pulse regime on the structure and optical properties of TiO2 nanolayers
(IOP Publishing, 2018-12)
TiO2 films were deposited onto glass substrates by pulsed laser deposition (PLD) in high vacuum under monopulse and multipulse excitation. After deposition, a thermal treatment on air atmosphere was done to promote ...
Evaluation of pure and Ag-doped TiO2 films in the photocatalytic activity of phenol
(2015)
Pure TiO2 films, modified by the addition of Degussa P25 powder and Ag-doped were synthesized using sol-gel route and immobilized in borosilicate support at different withdrawing rates and dipping time. They were characterized ...
Structural and luminescent properties of europium doped TiO2 thick films synthesized by the ultrasonic spray pyrolysis

Desenvolvimento de nanomateriais de TiO2/SiO2 pelo método sol-gel para aplicações nas áreas de energia e meio ambiente
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE QUÍMICAPrograma de Pós-Graduação em QuímicaUFMG, 2019-07-30)
The objective of this work was to obtain xTiO2/(100-x)SiO2 thin films and particles (with x = 0, 20, 40, 60, 80 and 100%) by the sol-gel process for applications in energy and environment areas. The method of precursor ...
Estudo da atividade fotocatalítica de filmes finos multicamadas de TiO2/CeO2.
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia de Materiais, 2019-05-31)
The use of thin films in photocatalytic processes is widely studied because unlike materials in the form of powder, do not generate secondary residues. However, thin films must have good chemical stability and oxidative ...
Layer by layer TiO2 thin films and photodegradation of Congo red
(Elsevier B.V. Sa, 2011-04-30)
Layer by layer (LbL) self-assembled technique was used to fabricate TiO2 films onto glass and quartz slides. The LbL sequence was PAH/PSS/TiO2(PSS/TiO2)(5) (PSS = poly(sodium-4-styrene sulfonate), PAH = poly(allylamine ...

Crystallization and optical properties of CCTO thin films under pressure influence
(2012-08-20)
CCTO thin films were deposited on Pt(111)/Ti/SiO 2/Si substrates using a chemical (polymeric precursor) and pressure method. The pressure effects on the CCTO thin films were evaluated by XRD, FEG-SEM and optical properties. ...
