Abstract

The use of CO 2 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 CO 2 are briefly surveyed both in terms of (i) use of catalysis for CO 2 fixation and (ii) use of CO 2 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 CO 2 to fuels (hydrocarbons and alcohols) are also shown.
