The paper first synthesized choline chloride / urea room temperature ionic liquid and choline chloride / glycol room temperature ionic liquids using Fourier transform infrared spectroscopy (FT-IR) and its characterization . Secondly, the choline chloride / urea AuPPh3Cl and choline chloride / urea anhydrous CuCl2 system , using an electrochemical sacrificial anode , metallic gold, copper raw materials electrochemically prepared gold nanoparticles ( gold → gold nanoparticles ) , the possibility of nano- copper ( copper → nanometer copper ) . The results show that , in the above system , the control of the appropriate conditions, can be prepared to obtain the nano - gold, nano-copper . Metal salt content , electrolytic temperature , the cathode of the electrolytic morphologies , and using SEM, TEM, XRD, FT-IR, TG of the products were characterized . Choline chloride / ethylene glycol AgCl system , the possibility of using electrochemical sacrificial anode , as raw materials directly to the metallic silver electrolytic preparation of nano- silver ( of silver → nanometer silver ) . The results showed that the right conditions , can be prepared nano-silver . Silver salt content , electrolytic temperature , the cathode of the electrolytic morphologies , and using SEM, TEM, XRD, FT-IR, TG of the products were characterized . Choline chloride ionic liquid raw material is inexpensive , simple synthesis by choline chloride ionic liquid electrochemical preparation of nano- gold , silver , copper , hope to be able to be prepared directly from the metal nano metal ; results show that choline chloride ion not only can be used as the electrolyte liquid , but also as a dispersant and modifier , to prevent the agglomeration of nano - metal . Electrochemical preparation of nano- choline chloride ionic liquid metal to meet the requirements of the development of green chemistry , embodies the concept of environmental protection . Therefore, there is a certain significance in theory and practical application .
