| Popis: | Perovskite is an oxide alloy which has a structure of ABO3 (A = La, Nd, Sm, Gd; B = Fe, CO, Ni) and has an excellent catalytic activity and gas-sensitive properties. NdFeO3 and its derivatives are important candidates for gas sensors. In this study, the effect of molar ratio (x=0.1, 0.2 and 0.3) on crystal structure and morphology of Nd1+xFeO3 synthesized by solid state reaction method has been studied. Nd1+xFeO3 samples were prepared using Nd2O3 (99.99 %) and Fe2O3 (99.99 %) as precursors. All of the samples were characterized using XRD to identify the phase and using SEM to identify the morphology. The synthesized Nd1+xFeO3 samples showed that molar ratio strongly influences the intensity, FWHM, and crystalline size. The samples of Nd1+xFeO3 have homogenous morphology and have three major phases, i.e. NdFeO3, Nd(OH)3 and Nd2O3 with crystalline sizes of NdFeO3 of 137.0±0.1 nm, 152.2±0.1 nm and 137.0±0.1 nm for Nd1.1FeO3, Nd1.2FeO3, and Nd1.3FeO3, respectively. These results indicated that the sample of Nd1.2FeO3 was a good candidate for a gas sensor material. |
