摘要
提出了一种全新的纳米材料制备方法—支撑液膜法。常温常压条件下,在0.2mol/L的CuCl_2溶液和0.2mol/L的Na_2S溶液、以及含邻菲罗啉载体的支撑液膜组成的共同反应体系中进行反应,成功制备出Cu_7S_4纳米晶。经XRD、TEM等表征,产物的粒径范围为5～10nm,结构为六方晶型,晶胞参数为a=15.475、c=13.356.本文还对其光学性质及产物形成机理进行了初步探讨.
A novel fabrication method of Cu7S4 nano-crystals by supported liquid membrane (SLM) system was investigated. SLM consists of CHCl3 as solvent, o-phenanthroline as a mobile carrier and polymer membrane as supported template. The results indicated that Cu7S4 which has hexagonal structure with cell constant of a=15.475Angstrom and C=13.356Angstrom can be prepared at room temperature with 0.2mol/L CuCl2 and 0.2mol/L Na2S as reactants. The average size of Cu7S4 is about 7nm. In addition, the forming mechanism and optical properties of Cu7S4 were discussed.
