Nucleation and crystallization of titania nanoparticles in silica titania planar waveguides: A study by low frequency Raman scattering
(2004-07-28)
SiO2 (1-x) - TiO2 (x) waveguides, with the mole fraction x in the range 0.07 - 0.20 and thickness of about 0.4 μm, were deposited on silica substrates by a dip-coating technique. The thermal treatments at 700-900°C, used ...

Solventless preparation of thoria and its inclusion into SiO2 and TiO2: a luminescence and photocatalysis study
(American Chemical Society, 2021)
Thoria was prepared using a solid-state method from the macromolecular precursor Chitosan center dot Th(NO3)(4) (chitosan) and PS-co-4-PVP center dot Th(NO3)(4) (PVP). The morphology and the average size of ThO2 depend of ...
A hybrid organic-inorganic layered TiO2 based nanocomposite for sunlight photocatalysis
(The Royal Society of Chemistry, 2016)
A novel hybrid nanocomposite constituted of single TiO2 nanosheets sandwiched between stearic acid self-assembled monolayers was synthesized and tested in the photodegradation of methylene blue under sunlight. The product ...
Photocatalytic degradation of phenol using TiO2 nanocrystals supported on activated carbon
(Lima (Perú)PE, 2005-08)
It has been deposited titanium oxide on activated carbon (AC) in two forms as powder and as a pellet. This oxide was obtained using sol-gel process based on titanium isopropoxide and isopropyl alcohol. Nanocrystalline TiO2 ...
