Gas sensing properties of ZnFe2O4/ZnO screen-printed thick films

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

“…Particularly, ZnFe 2 O 4 nanostructure has generated a lot of interest owing to their potential applications in gas sensor, magnetic behavior, electrical characteristics and semiconductor photo catalysis [14][15][16][17]. For these applications the surface morphology of ZnFe 2 O 4 plays a vital role to tune their chemical and physical properties to the appropriate ones.…”

Role of CuO-ZnO Heterojunctions in Gas Sensing Response of CuO-ZnO Thick Films

“…The state of oxygen on the surface of metal oxide sensor undergoing the following reactions [27][28][29][30] …”

Nanostructured ZnFe2O4thick film as room temperature liquefied petroleum gas sensor

“…[7][8][9][10] Currently, it is a topic of increasing interest to study the gas sensing properties of ferrites. [11][12][13][14][15][16] Ferrites show very good surface reactivity and they have temperaturedependent surface morphologies. [17] They also show remarkable catalytic properties in oxidation reactions due to the high oxygen ion mobility at the film surface and thus are highly interesting for the development of sensors.…”

“…In particular, spinel structured ZnFe 2 O 4 in which the transition metal Zn was incorporated into the lattice of the parent structure of (Fe 2þ Fe 3þ O 4 ) was established as to be a promising material in detecting the reducing gases. [21] Other earlier reports about the application study of zinc ferrite as a gas sensing material include ZnFe 2 O 4 particles to H 2 S, [22] a directly deposited film to CO, [23,24] CdO-doped ZnFe 2 O 4 to ethanol, [25] a ZnO/ZnFe 2 O 4 thick film to propanol [26] and so on.…”
