Abstract
The present invention provides methods of intercalating a catalyst promoter to form a catalyst composition suitable for converting syngas into alcohols, such as ethanol. Effective conditions for promoter intercalation are provided herein. This invention also provides novel compositions that can be characterized by interplanar spacings of the promoter within the catalyst composition.
Claims34
A method of intercalating a promoter to form a catalyst composition, said method comprising:
- (a) providing a starting composition comprising a transition-metal chalcogenide;
- (b) providing a promoter comprising one or more elements selected from the group consisting of potassium, cesium, barium, strontium, scandium, yttrium, lanthanum, and cerium;
- (c) combining at least some of said starting composition with at least some of said promoter, thereby producing a precursor composition;
- and
- (d) subjecting said precursor composition to effective conditions for intercalating said promoter, thereby producing a catalyst composition.
A composition comprising MoS2, Co, and K, wherein said K is intercalated in layers of said MoS2 having an interplanar spacing of about 7 Å to about 8 Å.
A composition comprising MoS2, Co, and Cs, wherein said Cs is intercalated in layers of said MoS2 having an interplanar spacing of about 8.0 Å to about 8.8 Å.
