Rising atmospheric concentration of CO2 is forecasted to have potentially disastrous effects on the global climate changes and ocean acidification.  A catalytic process that utilizes CO2 as a feedstock to make methanol, carbon monoxide, or methane is potentially more desirable than sequestration.  In the current talk we will describe our recent results of CO2 conversion through heterogeneous catalysis, using approaches involving parallel efforts in density functional theory (DFT) calculations, surface science experiments on model systems, synthesis and evaluation of supported catalysts, and in-situ characterization of catalysts under reaction conditions.   We will compare three examples for the catalytic conversion of CO2, to methanol over Cu-based oxides, to methane over bimetallic alloys, and to CO over metal carbides.  We will discuss general trends, challenges and opportunities for the catalytic conversion of CO2.
