Heterogeneous Catalytic Reactions with CO2: Status and Perspectives

The use of CO2 as feedstock for producing chemicals is not only interesting to contribute to mitigation of greenhouse gas emissions, but an interesting challenge to explore new concepts and new opportunities for catalysis and industrial chemistry. The present state and perspectives in heterogeneous catalytic reactions with CO2 are briefly surveyed both in terms of (i) use of catalysis for CO2 fixation and (ii) use of CO2 in heterogeneous catalytic reactions as mild oxidant, H-transfer agent and catalyst surface modifier. Discussion is limited to heterogeneous gas-solid catalytic reactions. Some results and opportunities for gas-phase photoelectrocatalytic conversion of CO2 to fuels (hydrocarbons and alcohols) are also shown.
