Synthesis and characterization of rough electrochromic phosphotungstic acid films obtained by spray-gel process
(Lima (Perú), 2003-07)
Rough electrochromic phosphotungstic acid (PWA) films were fabricated by spraying a gel of phosphotungstate anions with a molar ratio of P:W = 1:12 onto glass substrates precoated with transparent and electrically conducting ...
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 thin films obtained by spray-gel technique
(Lima (Perú), 2004-08)
Combining the spray pyrolysis and the sol-gel techniques (spray-gel) gives the possibility to produce very rough and highly diffuse films, under appropriate conditions. This technique is suitable for producing multifunctional ...
Spray pyrolysis deposited zinc oxide films for photo-electrocatalytic degradation of methyl orange: influence of the pH
(Lima (Perú), 2003-07)
Zinc oxide films were made by spray pyrolysis equipped with an optical system for in-situ thickness measurement; zinc acetate water solution was used as spraying solution. The pH of the spraying solution was modified in ...
