The oxalate co-precipitation method was used to prepare nanocrystallite ferrites with Nd3+ added to the general formula Mg1 – xCdxFe2O4 (x 0.5). FTIR, XRD, and SEM were all used to characterize the samples. According to XRD, the structure is cubic spinel with orthoferrite (NdFeO3) as a secondary phase. The crystallite size is 36.79 nm. SEM analysis of surface morphology indicates a grain size of 0.38 m. There are two strong absorption bands observed in the FTIR spectrum in the range of 350-800 cm – 1. We were able to detect various gases such as Cl2, LPG, and ethanol using the gas sensor from room temperature to 500 C. For 100 ppm ethanol gas at 500 C, the Mg0.5Cd0.5Nd0.01Fe1.99O4 composition has the greatest response. Mg-Cd ferrite sensor samples with Nd3+ added show good response and recovery time. Material composition, test gas, and grain size determine the time to complete the test. |
