PREPARATION OF BIFUNCTIONAL CATALYSTS

Catalyzed reactions are usually a combination of various reaction pathways that require catalysts to possess more than one chemical function. These reaction types and catalyst functions are reviewed and bifunctionality of catalysts is exemplified in the ensemble control effect for oxidation of carbons to CO/CO2, double redox oxide catalysts for partial oxidation of methane, base-hydrogenation catalysts for methanol and higher alcohol synthesis as well as the water gas shift reaction, hydrogenation-CO insertion catalysts for higher alcohol synthesis, and acid-hydrogenation catalysts for the synthesis of ethers.
