Nanocrystalline nickel ferrite thick film as an efficient gas sensor at room temperature

Room-temperature chlorine gas sensor based on CdSnO3 synthesized by hydrothermal process

“…In reactions (3) and (4) In this work, the working temperature of CdSnO 3 sensor is room temperature. At room temperature, there would be no oxygen adsorption [3,25], so the oxygen adsorption-desorption mechanism is not employed to sense the chlorine gas. Thus, the reactions (5) and (6) of chlorine gas sensing response of the oxides' surface are favorable mechanism in the present case.…”

Magnetic, electric and thermal properties of cobalt ferrite nanoparticles

“…Recently, nano ferrites have shown gas sensing capability [5][6], as well as photocatalytic and catalytic activity toward the degradation of organic matters and oxidative reactions in presence of reducing gases [7][8][9]. This multifunctional character of ferrites has potential application in the field of sensors, transducers and actuators [10][11][12][13][14].…”

Nanocrystalline Nickel Zinc Ferrite as an efficient alcohol sensor at room temperature

“…Presence of both nanostructured grain size and porosity, increases the specific surface area making it a suitable material for vapour sensing applications. It is known that samples with higher specific surface have higher response to the organic vapour [23]. …”
