A New Synthesis and Characterization of NdNiO3 Perovskite Nanoparticles via Coprecipitation Method

Abstract This study aims to synthesize NdNiO3 perovskite nanoparticles calcined at different temperatures via coprecipitation method in the presence of sodium hydroxide as a precipitating agent and polyethylene glycol as a surfactant. The products are characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR), and Surface area analyzer (SAA). The phase composition by XRD indicates that NdNiO3 is formed at 900 °C. The crystallite size using Scherrer equation shows crystallite size of NdNiO3 in ranging of 44–72 nm. The FTIR spectra indicates O–Ni–O vibration led to NdNiO3, in products calcined at 900 °C, with the wavenumber of 634 cm-1. The NdNiO3 exhibits a BET surface area of 133.79 m2 g-1 and a BJH pore volume of 0.121 cc g-1 with the average particle size of 14.10 nm. All results show that the synthesis of NdNiO3 via coprecipitation method is a suitable method to produce fine surfaces and pores with nanosized particles.
