Hydrothermal Synthesis of Rod-Like LaOCl Nanoparticles from New Precursors

Abstract

Using the hydrothermal method, rod-like lanthanum oxychloride nanoparticles were synthesized by the reaction of LaCl 3 .7H 2 O, ethylenediamine, and hydrazine. Ethylenediamine and hydrazine with pH management can control the particle growth and have an important role in the formation of rod-like structures. The morphology and microstructure of the obtained products were characterized by X-ray diffraction, energy-dispersive X-ray spectroscopy, fourier transformed infrared spectrum, and transmission electron microscopy The formation mechanism of the LaOCl nanostructures was also proposed.
