Sintesis dan Karakterisasi Material Nano-Perovskite Neodymium Iron Oxide (NdFeO3)

Abstract

Abstrak Sintesis nano-perovskite oksida neodimium besi (NdFeO 3) telah berhasil dilakukan dengan metode presipitasi menggunakan surfaktan EG (ethylene glycol) sebagai material pelapis. Senyawa NdFeO 3 dikarakterisasi analisis gugus fungsi kimia dengan FTIR (fourier transform infrared spectroscopy), analisis morfologi dengan SEM (scanning electron microscopy), analisis kristalinitas dan ukuran partikel dengan XRD (X-ray diffraction) dan TEM (transmission electron microscopy). Pengamatan SEM dan TEM menunjukkan bahwa hasil sintesis membentuk nanostruktur berbentuk bulat dengan ukuran diameter pada rentang 15 sampai 20 nm. Spektra XRD mengonfirmasi bahwa fasa NdFeO 3 membentuk struktur orthorombik dan perovskite. Abstract Nano-perovskite synthesis of neodymium iron oxide (NdFeO 3) was successfully performed using a precipitation method using the EG (ethylene glycol) surfactant as a coating material. The NdFeO 3 compound was characterized by functional group analysis using FTIR (four transforms infrared spectroscopy), morphology analysis using SEM (scanning electron microscopy), crystallinity and particle size analysis using XRD (x-ray diffraction) and TEM (transmission electron microscopy). SEM and TEM research shows that the synthesized substance formed a sphere-like nanostructure with a diameter varying from 15 to 20 nm. The XRD spectra indicated that the NdFeO 3 phase formed an orthorhombic and perovskite structure.
