Synthesis of CuS Nanoparticles in Water-in-Carbon Dioxide Microemulsions

摘要: The formation of CuS nanoparticles from Cu(NO3)2 and Na2S by the mixing two separate water-in-carbon dioxide (W/C) microemulsions supported sodium salt bis(2,2,3,3,4,4,5,5-octafluoro-1-pentyl)-2-sulfosuccinate (di-HCF4) was investigated. At a water-to-surfactant ratio 10 copper concentration 7.8 mM in aqueous phase, size sulfide particles ranged 4 to 6 nm. temperature−pressure phase diagrams W/C at various electrolyte concentrations were also determined. presence electrolytes found not affect cloud-point pressures significantly, even high concentrations.
