Highly sensitive formaldehyde chemical sensor based on hydrothermally prepared spinel ZnFe2O4 nanorods

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

“…Extrapolation of linear region of the plot along the X-axis gives the corresponding direct band gap and found 3.80 eV. This value of optical band gap matches well with the value reported by Rahmam et al [25]. He observed the absorption peak of zinc ferrite nanorods at 323 nm, which is correspond to the characteristic absorption peak.…”

“…Sutka et al [23] demonstrated that the gas sensing properties of a spinel ferrite complex metal oxide semiconductor can be improved by controlling iron stoichiometry. Rahman et al [25] made the considerable effort for the growth and development of face-centered-cubic spinel zinc ferrite nanorods using hydrothermal method at room condition. Sutka et al [26] presented an easy development of cheap, sensitive and integrable spinel zinc ferrite thin film gas sensors for the detection of ethanol.…”

“…Sutka et al [26] presented an easy development of cheap, sensitive and integrable spinel zinc ferrite thin film gas sensors for the detection of ethanol. Thus most of the studies reported in the literature present the sensing response at relatively high temperatures [20][21][22][23][24][25][26].…”

“…The LPG sensing characteristics of ZnFe 2 O 4 thin film were investigated at room temperature which is more reliable, stable and robust in comparison to the earlier investigated sensors [20][21][22][23][24][25][26]. Detection of LPG at room temperature is very helpful for the chemical industries and research laboratories.…”

Synthesis and characterization of novel spinel Zn 1.114 La 1.264 Al 0.5 O 4.271 nanoparticles

“…The size dependent gas sensing properties of spinel iron oxide nanoparticles was also investigated [30]. A highly sensitive formaldehyde chemical sensor based on hydrothermally prepared spinel ZnFe 2 O 4 nanorods has been reported [31]. The LiNi 0.5 Mn 1.5 O 4 spinel (as cathode) and Si nanoparticles (as anode) were combined for utilizing in an advanced Li-ion battery that yielded much greater specific capacity than most existing Li-ion batteries [32].…”
