研究了烷基羧酸银盐与伯胺的可控热分解法制备银纳米粒子。制备了一系列烷基羧酸银（C_7H_（15）COOAg、C_13 H_（27）COOAg和C_17 H_（35）COOAg），并在各种烷基胺（C_8H_（17）NH_2、C_12 H_（25）NH_2和C_18 H_（37）NH_2）存在下，在120 ℃或180 ℃下，在无溶剂条件下进行了这些烷基羧酸银的热分解反应。提供由烷基羧酸盐和烷基胺稳定的球形银纳米颗粒。纳米颗粒的尺寸和粒径取决于前体、烷基羧酸盐和烷基胺的烷基链长度。(c)2006年爱思唯尔公司All rights reserved.
Controlled thermolysis of silver alkylcarboxylates with primary alkylamines was investigated as a facile synthetic method of silver nanoparticles. A series of silver alkylcarboxylates, C7H15COOAg, C13H27COOAg, and C17H35COOAg, have been prepared and the thermolysis of those silver alkylcarboxylates in the presence of various alkylamines, C8H17NH2, C12H25NH2, and C18H37NH2, with no use of solvent was conducted at 120 or 180 degrees C for 5 h. providing spherical silver nanoparticles stabilized by alkylcarboxylates and alkylamines. The size and dispersibility of nanoparticles depend on the alkyl chain length of the precursors, alkylcarboxylates and alkylamines. (c) 2006 Elsevier Inc. All rights reserved.
