Effect of Mn substitution on acetone and ammonia sensing in CoFe2O4 nanoparticles
Mn has substituted part of Fe in cobalt ferrite (CoFe2O4) and resultant material has been abbreviated as CFMO (CoFe1.7Mn0.3O4). Chemical co-precipitation route has been followed for synthesis. X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive x-ray spectroscopy (EDX), I-V measurement were performed for sample characterization. The influence of Mn substitution was seen in lowering the operating temperature for both acetone and ammonia gas sensing with high response as well as very fast response and recovery timealong with temperature dependent selectivity.
