摘要

在非离子表面活性剂的反向胶束中,用氨水作为碱式硝酸铜的沉淀剂和四乙基硅烷水解的催化剂,合成了尺寸均匀的碱式硝酸铜@二氧化硅[Cu2(OH)3NO3@SiO2]纳米盘,用扫描电子显微镜、高分辨透射电子显微镜和X射线衍射方法表征了Cu2(OH)3NO3@SiO2纳米盘的结构,讨论了其形成机理,进一步探索了其转化为氧化铜@二氧化硅(CuO@SiO2)的热稳定性。

Abstract

Cu2(OH)3NO3@SiO2 nanodisks were prepared by one-pot synthesis through in-situ reaction between Cu(NO3)2 and ammonia in the reverse micelle,followed by TEOS hydrolysis.The shape transformation of Cu-SiO2 composite nanoparticles from spheres to disks was realized in reverse micelle by controlling ammonia concentration.The disk-shape of product was determined by hard template of layered Cu2(OH)3NO3 compound and the size was limited by the micelle.The materials were characterized by scanning electron microscope (SEM),transmission electron microscope (TEM) and X-ray diffraction (XRD).The nanodisk was an important raw material for Cu,Cu2O and CuO,@SiO2,which had an ultrahigh thermal stability.
