Gas-sensing properties of nanocrystalline TiO2

A Brownian Dynamics Simulation to Predict Morphology of Nanoparticle Deposits in the Presence of Interparticle Interactions

“…Nanostructured deposits and coatings are finding a multitude of applications in photocatalytic reaction systems (SahleDemessie et al 1999), photosensitized solar cells (O'Regan and Gratzel 1991), and sensors (Lin et al 1997;Kennedy et al 2003) due to their unique physical, chemical, optical, and electronic properties. In most applications, morphology of the nanostructured deposit plays an important role in their optimum functionality.…”

Hg-doped TiO2 nanostructures thin film prepared by sol–gel method for gas sensing applications: Correlation between the structural and electrical properties

“…Also, there have been very recent reports of gas sensing properties of TiO 2 prepared by Liquid Phase Deposition (LPD) toward NH 3 gas sensing [14]. The titanium doped with various transition metals such as Pt [15], La [16], Ga [17], Nb [18] and Au [19] have been reported to increase its characteristic of sensor response. However, Wang In the present study, we report the study of the structure, surface and electrical (gas sensing) properties of Hg-doped TiO 2 thin films prepared by sol-gel technique as a function of effect doping and annealing temperature.…”

Effect of TiCl4 treatment on the refractive index of nanoporous TiO2 films

“…Among them, TiO 2 has been utilized in a variety of applications such as solar cells [1][2][3][4], photocatalysis [5][6][7], optical coatings [8], batteries [9,10], and sensors [11,12], on the basis of its affordability, availability, and chemical stability. TiO 2 has a large band gap (3.0-3.2 eV), and its absorption coefficient in the visible range is consequently very low.…”
