CuO nanoparticles were synthesized by using microreactors made of Triton X-100/n-hextnol/cyclohexane/water W/O microemulsion system. Basic synthesis parameters were determined. The results of thermo gravimetric/differential thermal analysis(TG/DTA) of the precursor products indicated that the proper calcination temperature was about 500 ℃. The nanoparticles were characterized by X-ray diffraction(XRD), transmission electron microscopy(TEM) and UV-visible spectra. It was indicated that the grain size was highly dependent on the ratio of water to surfactant(R). With the R value increasing, the particles size became larger.
