Claim 6:
7. A method of making a catalyst for synthesizing ammonia, comprising:
providing a support comprising a porous tube yttria-stabilized zirconia (YSZ);
loading at least one of a transition metal and a transition metal oxide comprising ruthenium (Ru) onto the support using wet impregnation; and
loading at least one of an alkali metal and an alkaline-earth metal including Barium (Ba) as a promoter onto the support using wet impregnation, wherein the Ru-supported and Ba-promoted YSZ has an activation energy Ea of no more than about 46.2 kJ/mol for synthesis temperatures ranging between 300 degrees Celsius (° C.) and 450° C.
