Title:
ELECTROCHEMICAL METHOD FOR MANUFACTURING ONE OR MORE OF SILICON NANOPOWDER, SILICON NANOWIRE AND SILICON NANOTUBE
Document Type and Number:
WIPO Patent Application WO/2010/051759
Kind Code:
A1
Abstract:
The present invention discloses an electrochemical method for directly manufacturing one or more of silicon nanoparticles, silicon nanowires and silicon nanotubes from a compound SiX or a mixture containing the compound SiX. It is characterized in that a compound SiX or a mixture containing the compound SiX acts as a cathode, the cathode together with an anode can be put into an electrolyte containing metal compound fused salt, and then one or more of silicon nanoparticles, silicon nanowires and silicon nanotubes can be prepared on the cathode by applying a voltage between the cathode and the anode and by controlling the reaction conditions. The present invention is of short production procedure, no pollution and easy to handle, in addition, it is easy to successively produce with conveniently available raw materials and low-cost production facilities.
