Titanium dioxide nanoparticles obtained by sol gel method: Effect of the catalyst acids
(Instituto Peruano de Energía Nuclear, 2010-11)
Titanium dioxide nanoparticles have been obtained by sol-gel process. Titanium isopropoxide was hydrolized in acidic medium at pH values between 0.5 and 1. The hydrolysis was catalyzed with HCl, HNO3 or HClO4, and studied ...
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 ...
