Nanostructured Spinel ZnFe2O4 for the Detection of Chlorine Gas

Nanostructured Spinel ZnFe2O4 for the Detection of Chlorine Gas

Semiconductive nanometer-size material ZnFe2O4 was synthesized by a solution combustion reaction of inorganic reagents of Zn(NO3)3. 6H2O, Fe(NO3)3.9H2O and Urea as a fuel. The process was a convenient, environment friendly, inexpensive and efficient preparation method for the ZnFe2O4 nanomaterial. E...

Subjects:
Fe(NO3)3.9H2O and Urea as a fuel. The process was a convenient
environment friendly
inexpensive and efficient preparation method for the ZnFe2O4 nanomaterial. Effects of the calcining temperature on the phase constituents characterized by TG-DTA
X-ray diffraction (XRD) was used to confirm the material structure
The as-prepared samples were further characterized by scanning electron microscopy (SEM) equipped with energy-dispersive X-ray spectroscopy (EDX)
transmission electron microscopy (TEM). To depict the crystallite microstructure. Conductance responses of the nanocrystalline ZnFe2O4 thick film were measured by exposing the film to reducing gases like Acetone
Ethanol
Ammonia (NH3)
Hydrogen (H2)
Hydrogen sulphide (H2S)
Chlorine (Cl2) and Liquefied petroleum gas (LPG). It was found that the sensors exhibited various sensing responses to these gases at different operating temperature. Furthermore
Solution combustion reaction
Synthesis
ZnFe2O4 nanoparticles
