摘要:
The present invention relates to a method for manufacturing metal nanoparticles containing rod-shaped nanoparticles, the method including: producing metal oxide nanoparticle intermediates having at least rod-shaped metal oxide nanoparticles by heating a mixture of a nonpolar solvent, a metal precursor and an amine including secondary amine at 60-300° C.; producing metal nanoparticles by adding a capping molecule and a reducing agent to the mixture and heating the result mixture at 90-150° C.; and recovering the metal nanoparticles.According to the present invention, the shape of metal nanoparticle can be controlled by mixing primary amines or secondary amines as proper ratio without using apparatus additionally, as well as, the size of metal nanoparticle can be controlled to several nm.
摘要(中):
本发明涉及一种制造含有棒状纳米颗粒的金属纳米颗粒的方法,所述方法包括:通过加热非极性溶剂,金属前体和胺的混合物来生产至少具有棒状金属氧化物纳米颗粒的金属氧化物纳米颗粒中间体 包括在60-300℃的仲胺。 通过向混合物中加入封端分子和还原剂制备金属纳米颗粒,并将结果混合物在90-150℃下加热。 并回收金属纳米粒子。 根据本发明,金属纳米颗粒的形状可以通过混合伯胺或仲胺作为适当比例而不使用另外的装置,以及金属纳米颗粒的尺寸可以控制到几nm来控制。
