“…The nanocomposite films are complete inactive under dark conditions due to the practical absence of the oxide at the material surface. TiO 2 performance appears highly efficient under UV-B and UV-A wavelengths (280-380 nm) [35] and results displayed in Fig. 7 provide conclusive evidence of this.…”

“…From a toxicological point of view greater generation of ROS and other important characteristics of photocatalyst as its size, surface area, crystallinity, shape, solubility and agglomeration/aggregation state are important. However, it is also believed that the co-presence of both anatase and rutile phases is important for photacatalytic effi ciency 19, 21 . Better bacterial reduction was achieved for photocatalysts, which consisted from 3.0 to 4.1% of rutile (from 97 to 95.9 anatase phase respectively) than for single-phase titania.…”

“…Com esse fim, sistemas porosos de níquel/PVA têm sido descritos na literatura [16] . Em adição às aplicações anteriores descritas [17] , um uso bastante comum para as nanopartículas de semicondutores (óxido de zinco/dióxido de titânio) é o de bloqueadores de radiação ultra-violeta, com potencial aplicação como cosméticos para proteção solar, dados os efeitos nocivos da radiação ultravioleta sobre a pele humana. É sabido que a radiação solar compreende a região de raios-X até ondas de rádio e que a radiação ultravioleta é classificada em três tipos: UVA, UVB e UVC.…”
