実験手順
Each of the mixtures of copper nitrate and zinc nitrate at a Zn/(Zn+Cu) atomic ratio of 0.1, 0.2, 0.3, 0.5 and 0.67, respectively, was dissolved in an ionexchanged water at a concentration of 20 wt %. Separately, a 20 wt % aqueous solution containing a stoichiometric amount of sodium carbonate was prepared. The resulting sodium carbonate solution was added dropwise to the solution of nitrate mixture while stirring in a stirring tank to produce a precipitate of basic copper carbonate and basic zinc carbonate. The precipitate was filtered, washed with water and dried at 120° C. for 10 hours. The precipitate was then calcined at a temperature of 350° C. for 5 hours to obtain five mixtures of cupric oxide and zinc oxide having different proportions.
