SiOxCyHz-TiO2 Nanocomposite Films Prepared by a Novel PECVD-Sputtering Process
(ABM, ABC, ABPol, 2021-07-05)
Recently, there has been growing interest in the incorporation of particles in plasma deposited thin films to creation of multifunctional surfaces. In this work a new hybrid methodology based on the plasma enhanced chemical ...
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 ...
Síntese de materiais compósitos TiO2-SiO2 via sol-gel para adsorção de água
(Universidade Federal de Minas GeraisUFMG, 2014-01-15)
The presence of water can trigger serious damage in various branches of industry. The need for humidity control led to the development of a number of water adsorbent materials. Although widely used these materials have a ...
