Fabrication of Cu7S4 Nano-crystals with Supported Liquid Membrane

Abstract

Abstract: A novel fabrication method of Cu₇S₄nano-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=15.475Aand c=13.356Acan 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.

Key words: supported liquid membrane, nano-crystals, Cu₇S₄, mobile carrier
