Title:
ELECTROLYTIC DEPOSITION METHOD FOR NANO-SIZE METAL COBALT FINE PARTICLES
Document Type and Number:
WIPO Patent Application WO/2004/040041
Kind Code:
A1
Abstract:
Although cobalt is used for a catalyst, a secondary-battery electrode material, a magnetic material or the like, almost no report is available on an efficient production method for a cobalt single-crystal whisker and nano-size metal cobalt fine particles in other configurations. An electrolytic deposition method for nano-size metal cobalt fine particles characterized by comprising the steps of electrolyzing an aqueous solution of cobalt amine complex [Co(NH3)6]Cl3 within an electrolytic potential range of -0.90 to -1.25V with respect to a saturated calomel reference electrode, and depositing metal cobalt on a cathode. A metal cobalt single-crystal nano-wire or a leaf-structure crystal of metal cobalt is deposited.
