Highly-ordered mesoporous titania thin films prepared via surfactant assembly on conductive indium–tin-oxide/glass substrate and its optical properties

Block copolymer-templated synthesis of highly organized mesoporous TiO2-based films and their photoelectrochemical applications

“…Currently various heat-resistant substrates such as Pyrex glass [16,17,45,66], fused silica [51], transparent conductive oxide (TCO) [67][68][69][70][71], quartz [46], stainless steel [72][73][74], Ti foil [50], and silicon [15,75,76] have been employed for film deposition. The nature of coating substrates, particularly the surface roughness, has found to exert an influence on the mesostructural regularity of the mesoporous TiO 2 films [77].…”

The Effect of Tween® Surfactants in Sol-Gel Processing for the Production of TiO2 Thin Films

“…Previously we have reported the use of Brij ® surfactants in a non-aqueous sol-gel process to produce TiO2 thin films with an increased average particle size and increased surface roughness, whereby such structural changes led to an increase in the photocatalytic activity of produced TiO2 thin films [13]. The use of such non-ionic surfactants in sol-gel processing is a commonplace strategy for the direct control of particle size and shape during the growth phase for the enhancement of resulting properties [14,15]. Due to their amphiphilic nature, surfactants act as pore-directing agents that can enable the production of highly porous materials with specific pore size and structure.…”

“…Due to their amphiphilic nature, surfactants act as pore-directing agents that can enable the production of highly porous materials with specific pore size and structure. A wide variety of surfactants have been used in sol-gel processing for TiO2 thin film production including Brij ® surfactants [14,16], Triton™ X-100 [17], Pluronic triblock copolymers [14,15] and Tween ® 20 [18], which has been used in this investigation in comparison with Tween ® 40. This paper focuses on the use of Tween ® 20, 40 surfactants in a modified non-aqueous sol-gel method to investigate the effect of surfactant type and concentration on the subsequent microstructure and functional properties of TiO2 thin films.…”

Ordered mesoporous carbon/SnO2 composites as the electrode material for supercapacitors

“…Generally speaking, introducing of metal oxide into the channel of OMC is an effective way to enhance the specific capacitance. However, the high cost of hydrous ruthenium oxide prompted the research interest to focus on alternative cheap electrode materials (MnO x , NiO x , CoO x , SnO 2 , etc) [8][9][10][11][12][13][14][15][16][17][18] . Among these, SnO 2 is one of the most attractive materials due to its unique optical and electrical properties.…”

“…Among these, SnO 2 is one of the most attractive materials due to its unique optical and electrical properties. Tin(IV) oxide has a wide band gap (3.6 eV), n-type transparent semiconductor with rutile structure (P4/mnm), and it has many practical applications, such as gas sensors [12] , electrode for dye-sensitized solar cells [13] , and electrode for supercapacitors [14][15][16][17][18] .…”
