Synthesis of Sn doped ZnO/TiO2 nanocomposite film and their application to H2 gas sensing properties

Effect of Sn doping on the structural, optical and electrical properties of TiO2 films prepared by spray pyrolysis

“…From Tables 3 and 4, it is noticed that the efficiency of doped photoectrode based cell is much higher than that of pure photoelectrode based cell, because of the amount of chemisorptions of dye molecules on doped TiO 2 is much higher than of pure TiO 2 [5].Therefore, from the table, the FF and g % for the dye HR and HS-sensitized 6 at.%Sn-doped TiO 2 photoelectrode in I -/I 3 -electrolyte is purely due to the sensitization of dye to 6 at.% Sn-doped TiO 2 photoelectrode; making available maximum charge carriers and providing easy path for transport of charge carriers [44].…”

“…Among these materials, at present TiO 2 based applications such as sensors, solar cells, LEDs have been widely used because of their inert surface properties and high sensing abilities, long-time stability [2][3][4][5]. An introduction of small amount of impurities into TiO 2 induces a change in its structural, electrical and optical properties.…”

Synthesis and characterization of nanostructured undoped and Sn-doped ZnO thin films via sol–gel approach

“…In recent years, the metal oxide semiconductor functional materials have played an important role in the field of material science and technology [1,2]. Among metal oxide semiconductors, Zinc oxide (ZnO) has been extensively investigated due to its excellent physical properties and applications in commercial and scientific devices [1,[3][4][5][6][7].…”

“…Among metal oxide semiconductors, Zinc oxide (ZnO) has been extensively investigated due to its excellent physical properties and applications in commercial and scientific devices [1,[3][4][5][6][7]. This II-VI group n-type semiconductor is also one of the most important materials for the next generation devices [5] with a wide bandgap (3.37 eV) [1,2,8,9,[11][12][13]18], large exciton binding energy (60 meV) [10][11][12][13][14]18], low resistivity and high transparency in the visible range and high light trapping characteristics [8]. Due to these properties, this material is of considerable interest for practical applications such as photonic devices [15], gas sensors [3,8,9,15,16] and dye-sensitized solar cells [3,9,15,16,18] light emitting diodes (LED's), laser systems [3], transparent electrodes [3,8,9], piezoelectric device [8,16], flexible displays [17], surface acoustic wave devices (SAW) [9,16].…”

Comparative study of carbon dioxide sensing by Sn-doped TiO2 nanoparticles synthesized by microwave-assisted and solid-state diffusion route

“…These nanocomposites have been employed as hydrogen gas sensing materials. Chemisorption model was used to explain the H 2 sensing mechanism (Benkara et al 2013). Nanostructured Sn-doped TiO 2 has been reported by (Raji et al 2011), which is prepared by ball milling using SnO 2 and TiO 2 as raw materials.…”
