PROCESS FOR PRODUCING COMPOSITE MATERIAL OF METAL OXIDE WITH CONDUCTIVE CARBON |
摘要 |
Provided is a method whereby metal oxide nanoparticles having evenness of size are efficiently and highly dispersedly adhered to conductive carbon powder. This method comprises: a preparation step in which a reaction solution containing water, a compound with a transition metal selected from the group consisting of Mn, Fe, Co, and Ni, and conductive carbon powder and having a pH in the range of 9 to 11 is introduced into a rotatable reactor; a supporting step in which the reactor is rotated to apply shear stress and centrifugal force to the reaction solution, thereby yielding a core of a hydroxide of the transition metal and dispersing the thus-yielded core of a hydroxide of the transition metal and the conductive carbon powder and simultaneously supporting the hydroxide of the transition metal by the conductive carbon powder; and a heat treatment step in which the conductive carbon powder loaded with the hydroxide of the transition metal is heated to thereby convert the hydroxide supported by the conductive carbon powder into an oxide nanoparticle. |
