Potassium hexacyanocobaltate (4.0 g) is dissolved in deionized water (150 mL) in a beaker. Zinc chloride (10 g) is dissolved in deionized water (15 mL) in a second beaker. The aqueous solutions are quickly combined and magnetically stirred for 10 min. The precipitated solids are isolated by centrifugation. The solids are reslurried in deionized water (100 mL) for 10 min. with stirring, and are again recovered by centrifugation. The catalyst is dried in a vacuum oven at 50° C. and 30 in. (Hg) to constant weight. This catalyst is identified as Catalyst A, and has the powder X-ray diffraction pattern shown in FIG. 4.
