Abstract

The invention discloses a synthetic method for a neodymium sulfide nanoneedle, and belongs to the technical field of nanometer material preparation. The synthetic method comprises the following steps: using sodium sulfide, neodymium trifluoromethanesulfonate, ethanediamine and dioctyl sodium sulfosuccinate as raw materials, using water as a solvent, after uniformly mixing sodium sulfide, neodymium trifluoromethanesulfonate, ethanediamine and dioctyl sodium sulfosuccinate with water, putting the mixture in a reaction container and sealing, and carrying out heat preservation for 2-12 h at the temperature of 300-400 DEG C to obtain a target product, namely the neodymium sulfide nanoneedle. The adopted synthetic method has the characteristics of simple process, low reaction temperature, short consumed time and no environmental pollution; meanwhile, the prepared neodymium sulfide nanoneedle has a good application prospect in the fields of coatings, photocatalytic materials, adsorbents and thermoelectric materials.

Description

technical field [0001] The invention belongs to the technical field of nanomaterial preparation, and in particular relates to a synthesis method of neodymium sulfide nano needles. Background technique [0002] Rare earth sulfides have high melting point, low thermal conductivity, bright color, photocatalysis and the ability to transform between metal conductors and insulators through self-doping, and have good application prospects in the fields of coatings, photocatalytic materials and thermoelectric materials. [0003] Neodymium sulfide is an important rare earth sulfide. Traditionally, elemental sulfur and neodymium are used as raw materials, and neodymium sulfide powder can be prepared by high-temperature solid-state reaction. Literature (C.M.Vaughan~Forster, W.B.White.Powder preparation and sintering characteristics of rare~earth sesquisulfide ceramics.J.Am.Ceram.Soc.80(1997)273~276.) reported a preparation method of neodymium sulfide powder, In this method, a small-si...
