Solar photocatalytic degradation of phenol using pyrolitic TiO2 films deposited inside a tubing
(Lima (Perú), 2005-08)
Solar photocatalytic degradation of phenol was obtained using TiO2 films deposited inside glass tubing. TiO2 thin films inside tubing were obtained by spray-gel technique using a titanium isopropoxide solution conveniently ...
Photocatalytic degradation of phenol using TiO2 nanocrystals supported on activated carbon
(Lima (Perú), 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 ...
Diseño y construcción de un sistema para la supervisión in-situ del crecimiento de una película delgada de ZnO fabricada por rociado pirolítico
(Lima (Perú), 2005-08)
Se implementó un sistema que supervisa in-situ el espesor y calcula el perfil de una película delgada fabricada por la técnica de rociado pirolítico. El sistema se basa en la medición de la reflexión de un haz láser que ...
The influence of the ethanol/water molar ratio in the precursor solution on morphology and photocatalytic activity of pyrolytic ZnO films
(Lima (Perú), 2005-08)
Zinc oxide films were fabricated by a home made spray pyrolysis system equipped with an optical set-up ensuring the in-situ control of the film growth. 0.1 M of zinc acetate diluted in a mixture of ethanol and water was ...
Highly porous tungsten-oxide-based films obtained by spray-gel for gas sensing applications
(Lima (Perú), 2005-08)
Highly porous mixed WO3–SnO2 films have been prepared from an aqueous solution of SnCl4.5H2O and polytungsten gel with a molar ratio of Sn/W from 0 to 1. These solutions were sprayed on to alumina substrates at 220 ºC. The ...
