Preparation of Ru/Se Nano-particles for Catalyst by W/O Reverse Micro-emulsion
The Rux Sey nano-particles were prepared by reducing RuCl3 and SeO2 using NaBH4 as the reducing agent in the W/O(Water/Oil) reverse micro-emulsion system. The products characteristics such as diameter, components and structure were investigated by Transmission Electronic Microscopy(TEM),Fourier Transform Infrared Spectroscopy (FT- IR) and X- ray Diffractometry (XRD). The results showed that the morphology and diameters of the prepared nano-particles were affected by molar ratio of water and surfactant (ω0), concentration of surfactant (n0) and methods of preparing these particles. The result from FT- IR demonstrated that RuCl3 was reduced completely, and the spectrum of XRD confirmed that the adding of Se had no impact on Ru crystal-plane but enhanced the intensity of diffraction peak.
