Influência do tipo de ácido e tempo de envelhecimento na atividade fotocatalítica de filmes finos de TiO2
TiO2 thin films were prepared by the sol-gel method using different acids (HCl and HAc), with a parallel evaluation of the gel ageing effects on the film properties. After the thermal treatments, the resulting materials were characterized through gravimetric analysis, UV-VIS spectrophotometry (from...
