Abstract

Metal oxide nanoparticles are usually synthesized using chemical materials that harmful for the environment. In this research, neodimium oxide nanoparticles (Nd 2 O 3 NPs) has been green synthesized by a facile and eco-friendly method using aqueous extract of Terminalia catappa leaf (TLE) as weak base source and Nd(NO 3 ) 3 as precursor. Phytochemical test of TLE showed the presence of flavonoid, alkaloid, polifenol and saponin. The formation of Nd(OH) 3 sol was observed by UV-Vis spectrophotometer. Nd(OH) 3 gel was heated and calcined to obtain Nd 2 O 3 NPs. Functional groups of TLE and Nd 2 O 3 NPs were characterized by Fourier transform infrared (FTIR) spectroscopy. The crystal structure and particle size of Nd 2 O 3 NPs were analyzed by X-ray diffraction (XRD) and transmission electron microscopy (TEM). UV-Vis spectrophotometry data were obtained to investigate the shift of wavelength and absorbance value. These are due to the interaction of hydrolysis reaction from alkaloids and Nd(NO 3 ) 3 to form Nd(OH) 3 . The dispersion of Nd 2 O 3 NPs in water showed an increasing wavelength due to the effect of nanoparticle size. The characterization of UV-Vis-DRS was conducted to obtain the energy band gap of Nd 2 O 3 NPs as 4.4 eV, with maximum wavelength, λ max 378 nm. Peak of TLE was broad and strong occurred at 3261 cm -1 as -OH group vibration, 1694 cm -1 as C=O group, 1359 cm -1 as -NH group, and 1056 cm -1 as C-O group. All of the data showed the functional groups of secondary metabolites in TLE. Spectrum of Nd 2 O 3 NPs occurred at 423 cm -1 as Nd-O bond vibration. The crystalline phase of Nd 2 O 3 NPs was determined by XRD, which has conformity with the characteristic peaks of Nd 2 O 3 -A as hexagonal phase (JCPDS No. 0282). Particle size of Nd 2 O 3 NPs using TEM was observed at approximately 40-60 nm.
