Liquefied petroleum gas sensing performance of cerium doped copper ferrite
Source abstract
Abstract
Abstract Undoped and cerium (Ce) doped nanocrystalline copper ferrite (CuFe 2 O 4 ) materials were synthesized via the molten-salt (M-S) method. Effects of Ce doping on the structural, morphological and gas sensing properties of the CuFe 2 O 4 ferrite have been investigated. X-ray diffraction (XRD) analysis revealed the formation of spinel CuFe 2 O 4 . Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) investigations showed that the synthesized ferrite is made up of very fine spherical nanoparticles. Moreover, the gas sensing properties of sintered samples were studied towards different reducing gases such as liquefied petroleum gas (LPG), acetone, ethanol and ammonia. The sample with 4% cerium doped CuFe 2 O 4 (Ce4) showed the maximum gas sensitivity (86%) towards LPG with fast response time of 5 s and good recovery time of 68 s.
