Decomption Synthesis of CuS and Cu₂O Nanomaterials in the Presence of PEG400

Department of Material Engineering, Nanjing Institute of Technology, Nanjing 211167, China

摘要: 本文报道了在表面活性剂PEG400存在下通过简单的热分解反应分别合成了硫化铜纳米粒子和氧化亚铜纳米方块, 硫化铜纳米粒子直径在11~20nm之间, 氧化亚铜纳米方块尺寸在300~00nm之间。用X射线衍射仪 (XRD) 和透射电子显微镜 (TEM)) 对产物的结构和形貌进行了表征。同时, 对产物的紫外—可见光吸收性能 (UV-vis) 作了测试, 结果表明, 硫化铜纳米粒子在430nm处有一个较为明显的肩峰, 氧化亚铜纳米方块在400nm处有较为明显的吸收峰, 两种材料与其本体相比均发生了蓝移。

Abstract: In the paper, CuS and Cu₂O nanomaterials were synthesized by a simple decomption reaction in the presence of PEG400.The CuS nanoparticles are about 11~20 nm in diameter and the Cu₂O nanocubes are 300~800nm in side length.The products were characterized by X-ray Diffraction (XRD) and Transmission Electron Microscopy (TEM).The UV-vis spectra of the CuS nanoparticles and the Cu₂O nanocubes exhibit the abvious absorption peaks at 430 and 400nm respectively, and show the distinct blue shift with compared to them of the bluks.The formation mechanism of the CuS nanoparticles and the Cu₂O nanocubes is also discussed in brief.
