摘    要:以聚乙烯吡咯烷酮为保护剂,以硝酸汞和硫代乙酰胺为原料,采用水热法合成了高分散的硫化汞(HgS)纳米颗粒,并通过TEM、XRD、XPS对其进行了表征。结果表明:水热法有利于提高HgS纳米颗粒的结晶性能;所制备的HgS为立方结构的β-HgS纳米颗粒,颗粒粒径小,平均粒径约为11.5nm,粒径分布范围窄,分散性能好,纯度高。

关 键 词:硫化汞纳米颗粒  高分子保护法  水热法  高分散

Abstract:Mercury sulfide(HgS) nanoparticles had been prepared by hydrothermal method using mercury nitrate and thioacetamide as starting materials and polyvinylpyrrolidone(PVP) as the protection reagent. The structure, particle size,and composition of the HgS nanoparticles were characterized using transmission electron microscopy(TEM), X-ray powder diffraction (XRD) and X-ray photoelectron spectrum (XPS). The results showed that hydrothermal method was an effective method to improve the crystal properties of HgS nanoparti- cles. The HgS obtained was/9-HgS nanoparticles with cubic structure, small particle size(average particle size was 11.5 nm),narrow particle size distribution, high dispersity and high purity.
Keywords:mercury sulfide nanoparticles  polymer protection method  hydrothermal method  high dispersive
