The (CH2O)n stoichiometry of biomass implies that its conversion to energy carriers and other petroleum-derived hydrocarbons centers on the removal of oxygen. This talk will discuss cases studies of deoxygenation chemistry on metal carbide catalysts. Specifically, the talk will include a discussion of (i) the potential for using CH4 – instead of molecular hydrogen – so that in essence, CH4 serves as a surrogate for molecular hydrogen for biomass deoxygenation while biomass serves as the oxygen carrier for hydrogen removal from CH4; and (ii) the site requirements and mechanism for selectively cleaving C=O and C-O linkages in sugar and lignin monomers for the synthesis of bulk and specialty chemicals.

Catalysis of the conversion of carbon dioxide to liquid fuels using solar and electrical energy is a global challenge that could impact the carbon balance by recycling CO2 as fuels. A related challenge is the direct conversion of chemical energy contained in liquid fuels to electrical energy in fuel cell applications. Recent results in the study of artificial catalysts for the chemical reduction of CO2 will be reviewed.
