TiO2/SiO2 Composite for Efficient Protection of UVA and UVB Rays Through of a Solvent-Less Synthesis
(Springer New York LLC, 2019)
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 ...
Desenvolvimento de materiais nanoestruturados processados pela técnica de Fiação por Sopro em Solução
(Universidade Estadual Paulista (Unesp), 2019-12-13)
A técnica de fiação por sopro em solução foi utilizada neste trabalho para a produção de fibras de PVDF/TiO2, PVDF/Ni, PVDF/Fe2O3@SiO2, TiO2/Ag e fibras puras de TiO2. Inicialmente, foi realizado um estudo sobre a influência ...
TiO2 Coating of High Surface Area Silica Gel by Chemical Vapor Deposition of TiCl4 in a Fluidized-Bed Reactor
(American Scientific Publishers, 2011-09)
TiO2 was deposited on high surface area porous silica gel (400 m2g−1) in a fluidized bed reactor. Chemical vapor deposition was employed for the coating under vacuum conditions with TiCl4 as precursor. Nitrogen physisorption, ...
