Abstract
The present invention provides a catalyst, comprising molybdenum; one or more first elements selected from a Group V, VI, VII, VIII, IX, X, and XI metal (e.g., silver, cobalt, nickel, copper, rhodium, ruthenium, iridium, palladium, niobium, and manganese); one or more second elements selected from sulfur, carbon, oxygen, phosphorus, nitrogen, and selenium; and optionally, one or more Group IA metals, wherein the molybdenum is present in an amount of 10-50 wt. % of the total amount of the one or more first elements, the molybdenum, the one or more second elements, and the Group IA metal, and methods of using said catalyst in the production of ethanol from carbon dioxide.
Claims75
A catalyst, comprising:
- molybdenum;
- one or more first elements selected from a Group V, VI, VII, VIII, IX, X, and XI metal (e.g., silver, cobalt, nickel, copper, rhodium, ruthenium, iridium, palladium, niobium, and manganese);
- one or more second elements selected from sulfur, carbon, oxygen, phosphorus, nitrogen, and selenium;
- and
- optionally, one or more Group IA metals,
- wherein the molybdenum is present in an amount of 10-50 wt. % of the total amount of the one or more first elements, the molybdenum, the one or more second elements, and the Group IA metal.
The catalyst of any one of the preceding claims, wherein the one or more first elements comprise nickel.
The catalyst of any one of the preceding claims, wherein the one or more first elements comprise silver.
The catalyst of any one of the preceding claims, wherein the one or more first elements comprise copper.
The catalyst of any one of the preceding claims, wherein the one or more first elements comprise niobium.
The catalyst of any one of the preceding claims, wherein the one or more first elements comprise manganese.
The catalyst of any one of the preceding claims, wherein the catalyst comprises the one or more first elements at a molar ratio of about 0.15 to about 2 relative to the molybdenum.
The catalyst of any one of the preceding claims, wherein the catalyst comprises cobalt at a molar ratio of about 0.15 to about 2 relative to the molybdenum.
