Nickel doped spray pyrolyzed nanostructured TiO2 thin films for LPG gas sensing

Synthesis of ZnGa2O4 assisted by high-energy ball milling and its gas-sensing characteristics

“…It is well known that LPG consists of CH 4 , C 3 H 8 , C 4 H 10 , etc. [35]. The overall reaction of LPG molecules with adsorbed oxygen species may be illustrated as follows:…”

Synthesis of Nickel-Doped TiO2 Thin Films and Their Structural and Optical Properties at Different Annealing Temperatures

“…Titanium oxide (TiO 2 ) thin films, owing to their excellent properties including, chemical stability, low cost, large optical band gap and photocatalytic activity at visible light [1][2][3][4], have attracted much attentions in recent years. Metal and nonmetal doping of TiO 2 have been used to extend the absorption edge towards the visible light range and to improve the photocatalytic activity [5][6][7][8].…”

“…Metal and nonmetal doping of TiO 2 have been used to extend the absorption edge towards the visible light range and to improve the photocatalytic activity [5][6][7][8]. Several physical and chemical methods have been reported for growth of TiO 2 and doped-TiO 2 thin films [1][2][3][4][5][6][7][8]. In this work, nickel doped TiO 2 thin films were grown on glass substrates by means of DC reactive magnetron sputtering.…”

Ni-doped TiO2 nanotubes for wide-range hydrogen sensing

“…Nakhate et al used hydrothermal method to prepare Ni-TiO 2 film and studied the effect of Ni doping concentration on the photoactivity for methylene blue degradation [20]. Patil et al found that the nanostructured 2.5% Ni-doped TiO 2 thin film was very sensitive to liquified petroleum gas at 250°C [21]. Park et al reported that electronic structure of Ni-doped TiO 2 oxide could have a paramagnetic ground state and Chen et al explored the ferromagnetic mechanism of Ni-doped TiO 2 by series of density functional calculations [22,23].…”
