柠檬酸钠溶液中金纳米粒子的简易制备

Synthesis of Gold Nanoparticals

以氯金酸为原料,柠檬酸钠为保护剂,制备了金纳米粒子;应用透射电镜和紫外-可见分光光度计对该实验样品进行了表征,结果表明,此类纳米粒子尺寸均匀、呈球形单分散分布。

With HAuCI4 as reactants,Na3C6H5O7 as protectant,gold nanoparticals were synthesized,TEM and UV-Vis spectroscopy were used to characterize the samples.The results indicate that the gold nanoparticals have uniform size and spherical monodisperse distribution.
