Description
We present the effect of cerium(Ce3+) at various concentrations ranging from 1-5 wt%, doped in CoNiFe2O4 for the detection of LPG and H2S prepared by the Sol-gel method. X-ray Diffraction confirms the cubic phase of all the samples, and no impurities were detected with a crystallite size range of 8 to 11 nm. Scanning Electron Microscopy (SEM) and Electron Dispersive X-ray Spectroscopy (EDS) depict that undoped and doped ferrite are spherical with only a few areas having nano-flakes like. The gas response of undoped and doped Ce3+ was investigated in the 225-275 °C temperature range. Undoped CoNiFe2O4 showed a low response. In contrast, the sample with Ce3+ had an improved response to LPG and H2S gases. Increasing the Ce3+ amount in CoNiFe2O4 is promising for making better sensors to detect gases.
