Synthesis of yttrium, lanthanum, neodymium, praseodymium, and lutetium alkoxides and acetylacetonates
摘要:
A convenient and practical method is proposed for the synthesis of lanthanide and yttrium alkoxides. The method involves dissolving the metals or their hydrides in a solution of dry HCl in the corresponding alcohol, with subsequent dehalogenation of the LnCl3 solution by an equivalent amount of alkali metal (Na, Li), The rare-earth alkoxides are easily converted into acetylacetonates Ln(acac)3 by the action of acetylacetone.

Nanowires of single crystalline neodymium oxide have been successfully synthesized under mild conditions using surfactant-assisted assemblies composed of laurylamine hydrochloride and neodymium alkoxide modified with acetylacetone. The nanowire structure was characterized by XRD, TEM, SEM, and nitrogen adsorption isotherms. Nd2O3 nanowires have a single crystalline structure with diameters ranging from 10 to 50 nm and lengths of several hundred nanometers. This newly developed synthetic method can be easily extended to other rare earth metal oxides.
