Abstract: Catalysts for hydrogenation of CO2 to dimethyl ether. These catalysts comprise 0.1-10 wt % per total catalyst weight of a catalytic material containing Pd (e.g. metallic palladium), 0.05-5 wt % per total catalyst weight of a promoter containing Ca (e.g. metallic calcium), as well as 85-99 wt % of CeO2 as a catalyst support. Methods of preparing and characterizing the catalysts as well as processes for catalyzing the hydrogenation of CO2 to dimethyl ether and other byproducts such as methanol, carbon monoxide, and methane portrayed by reactant conversion, product selectivity, and catalyst stability are disclosed.

Abstract: Systems and methods for ammonia decomposition catalysts are described. Systems and methods may include providing a first solution, where the first solution includes a first metal soluble salt of cobalt, nickel, iron, and a combination thereof; a second metal soluble salt of magnesium, calcium, strontium, barium, and a combination thereof; a third metal soluble salt of lanthanide elements, and a combination thereof; and a fourth metal soluble salt of aluminum, transition metals, alkali metals, and a combination thereof. The first metal oxide, the second metal oxide, the third metal oxide, and the fourth metal oxide may be co-precipitated from the first solution at a pH between approximately 6.0 and approximately 11.0 to form a hydrotalcite-like structured material. The co-precipitated material may be aged and dried. The aged, dried, co-precipitated material may be decomposed to form a final catalyst product.
