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 ...
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 ...
Surface morphology engineering of metal-oxide films by chemical spray pyrolysis
(Lima (Perú), 2007-08)
Chemical Spray Pyrolysis Technique and a combination of sol-gel and spray pyrolysis techniques have been used in order to monitor the morphology of metal-oxide-based thin films to be used as functional materials. We can ...
Síntesis y caracterización de nanopartículas de peróxido de cinc (ZnO2) obtenidas mediante la técnica de sol-gel
(Instituto Peruano de Energía Nuclear, 2011-10)
Nanopartículas de peróxido de zinc (ZnO2) fueron sintetizadas mediante la técnica de sol-gel, empleando acetato de zinc di-hidratado (Zn(CH3COO)2.2H2O) y peróxido de hidrógeno (H2O2) al 30 % en un medio acuoso. Durante la ...
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 ...
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 ...
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 ...
