Synthesis, characterization and performance of zinc ferrite nanorods for room temperature sensing applications

Preparation of Pd nanoparticle-decorated hollow SnO 2 nanofibers and their enhanced formaldehyde sensing properties

“…The size of Pd nanoparticles in Pd decorated hollow SnO 2 NFs, according to the high-resolution TEM, was several nanometers. As the size decreases, the catalytic activity of noble metal increases because of the manifold increase in surface area of the nanoparticles, which will enhance the rate of reaction/adsorption of gas on the sensing material and eventually increase the response [32][33][34]. And no other diffraction peaks corresponding to impurities were observed, which implied the absence of other impurities.…”

Liquefied petroleum gas sensing by Al-doped TiO2nanoparticles synthesized by chemical and solid-state diffusion routes

“…Singh et al demonstrated the room temperature sensing application of zinc ferrite nanorods for LPG. In this investigation, more variations in the electrical resistance were observed for LPG than for CO 2 gas, which indicates that the samples are more selective and sensitive towards LPG [5]. Jaiswal et al studied the enhancement of the gas sorption ability of a LPG sensor.…”

Fabrication and characterization of nanostructured (Sn–Ti)O2 pellets and films for liquefied petroleum gas sensing

“…As LPG was able to react with the adsorbed oxygen then the combustion products such as water depart, and a potential barrier to charge transport would be developed i.e., this mechanism involves the displacement of adsorbed oxygen species by formation of water. This can be understood by following reaction [46]:…”
