Abstract: The invention aims at producing metal oxide nanoparticles and carbon carrying metal oxide nanoparticles supported thereon in a highly dispersed state by an accelerated liquid-phase chemical reaction and providing electrodes containing the carbon and electrochemical devices provided with the electrodes. The accelerated liquid-phase chemical reaction is attained by applying a shear stress and a centrifugal force to reactants in a rotating reactor in course of the reaction. Further, the carbon carrying metal oxide nanoparticles supported thereon in a highly dispersed state is made from both metal oxide nanoparticles produced by an accelerated liquid-phase chemical reaction wherein a shear stress and a centrifugal force are applied to reactants in a rotating reactor in the course of the reaction and carbon dispersed in the rotating reactor by applying a shear stress and a centrifugal force. Electrochemical devices made by using the carbon carrying the metal oxide nanoparticles as the electrode have high output and high capacity characteristics.
