CATALYSTS AND METHODS FOR METHANOL SYNTHESIS FROM DIRECT HYDROGENATION OF SYNGAS AND/OR CARBON DIOXIDE

摘要

Nano-sized mixed metal oxide catalysts capable of producing methanol (CH₃OH) from carbon dioxide (CO₂) and hydrogen (H₂) or from carbon dioxide (CO₂), carbon monoxide (CO), and hydrogen (H₂), methods of making the catalyst, and uses thereof are described herein. The nano-sized mixed metal oxide catalysts can have a formula of: [Cu_aZn_bAl_cM_d¹]O_n where a is 20 to 80, b is 15 to 60, c is 1 to 25, d is 0 to 15 and n is determined by the oxidation states of the other elements is determined by the oxidation states, and M¹ can be yttrium (Y), cerium (Ce), tin (Sn), sodium (Na), bismuth (Bi), magnesium (Mg), or gadolinium (Gd).
