Surface modification of sol gel TiO2 surface with sputtered metallic silver for Sun light photocatalytic activity: Initial studies

Transparent and flexible films of new segmented polyurethane nanocomposites incorporated by NH2-functionalized TiO2 nanoparticles

“…So, many efforts have been made to overcome this problem and to enhance the filler-matrix compatibility through surface modification of the used nanoparticles [10][11][12][13]. So far, surface modified nano-TiO 2 particles have been widely used in the field of polymer-based nanocomposites [14][15][16][17][18][19][20]. The most research activities have been focused on the surface modification of nano-TiO 2 using silane coupling agents such as 3-aminopropyltriethoxysilane (APTS) [21][22][23][24][25].…”

Efficiency enhancements in Ag nanoparticles-SiO2-TiO2 sandwiched structure via plasmonic effect-enhanced light capturing

“…However, to date, the doping structure lacks reliable controllability. Recently, metallic nanostructures have been introduced into a semiconductor film (e.g., ZnO, InGaN quantum wells) for enhancement of light emission, photocurrent solar cells [11-14], and photocatalysts [15-17] by a strong plasmonic effect of metallic nanostructures. In order to maximize the utilization rate of the UV region of the sunlight, in this letter, we design a new composite structure to enhance the light absorption efficiency by coupling TiO 2 to Ag nanoparticles (NPs) embedded in SiO 2 formed by low-energy Ag ion implantation.…”

Band gap and morphology engineering of TiO2 by silica and fluorine co-doping for efficient ultraviolet and visible photocatalysis

“…It is well-known that doping of TiO 2 with transition-metal elements demonstrates obvious shifts in the light absorption [13][14][15]. It is well-known that doping of TiO 2 with transition-metal elements demonstrates obvious shifts in the light absorption [13][14][15].…”
