Abstract

Highly dispersed noble metal nanoparticles can be produced in solution, ionic liquids or withinvarious porous materials at room temperature using glow discharge plasma reduction. Theprepared nanoparticles were characterized with UV-visible absorption spectra (UV-vis), X-rayphotoelectron spectroscopy (XPS), transmission electron microscopy (TEM) equipped with anenergy dispersion X-ray spectrometer (EDX), catalytic reactions and others. The nucleation andgrowth of nanoparticles under the influence of the plasma are closely related with the highenergy electrons generated by glow discharge plasma. Because of its simple, economical andextremely time efficient synthesis procedure, this facile and one-step method will be verypromising as an alternative route for the preparation of metal colloids and supportednanoparticles, which would be significant for both fundamental and applied researches.
