Provided is a catalyst electrode, in particular an electrode comprising a nanocatalyst material, an electrochemical cell containing the catalyst electrode, and a method of making the catalyst electrode and electrochemical cell. The present invention is a method of making a catalyst electrode containing a transition metal nanocatalyst without using spray or pyrolysis, and a method of making an electrochemical cell with a catalyst electrode. The nanocatalyst is preferably at least partially oxidized to include at least an oxide shell before being mixed with the activated carbon and the binder in a liquid medium to adhere the nanocatalyst particles to the inner and outer surfaces of the activated carbon particles. A fine particle material containing particles. Oxidizing nanocatalyst particles allows nanocatalysts, activated carbon, and binders to be mixed in the air rather than in an inert gas atmosphere, avoiding the use of potentially dangerous liquid media such as highly volatile alcohols. Can do. [Selection] Figure 1 |
