CO and NO2 sensing properties of doped-Fe2O3 thin films prepared by LPD

A novel conducting nanocomposite obtained by p‐anisidine and aniline with titanium(IV) oxide nanoparticles: Synthesis, Characterization, and Electrochemical properties

“…These nanocomposite materials are especially important due to their bridging role between the world of conducting polymers and that of inorganic materials. Though inorganic semiconductors, such as SnO 2 [9], Fe 2 O 3 [10], V 2 O 5 [11], WO 3 [12]. Hence, combining these two kinds of materials to form composite may lead to a synergy effect and help to enhance each other, which are helpful for improving sensor properties such as thermal stability, lower operating temperature and fast response and recovery.…”

Microstructural characterization of CoMnFeO4thin films deposited by radio-frequency sputtering

“…In fact, their magnetic and electrical properties allow the use of these materials in information storage [1,2], in gas sensor [3,4] and in catalysts [5,6]. Spinels are often used in the form of thin films that are prepared by physical vapor deposition (PVD) techniques such as the radio-frequency sputtering.…”

Experimental and Theoretical Study of Low-Dimensional Iron Oxide Nanostructures

“…Tao and co-workers (1999) have studied the sensing characteristics of Y 2 O 3 -doped -Fe 2 O 3 towards hydrocarbon gases, H 2 and CO and found that the addition of Y 2 O 3 to -Fe 2 O 3 resulted in a little difference in the sensitivity and selectivity compared with those made of pure -Fe 2 O 3 . Neri et al(2002) have assessed the gas-sensing properties of Zndoped Fe 2 O 3 thin films prepared by liquid phase deposition method. They observed that the addition of metal Zn can increase the sensitivity of the Fe 2 O 3 thin film to NO 2 below 250 °C.…”
