CO2 utilization has received worldwide attention. Effective utilization of CO2 becomes an urgent challenge. As such

developing catalysts and catalytic processes for effective CO2 conversion will contribute positively to reducing net CO2 emission. Recent developments of catalysts for CO2 hydrogenation to methanol

CO2 methanation and CO2 reforming of methane have been briefly reviewed. In particular

novel catalysts developed through computational catalysis and intensified catalyst preparation were presented. The importance of CO2 anion in CO2 reduction has been discussed. The plasma enhanced catalyst preparation was used as an example to demonstrate the importance of the multi-disciplinary efforts. Catalysts with optimized structures for heat transfer performance and distribution of active sites for CO2 conversion have also been discussed. Because of the complexity of global warming

some issues (for example the influence of change in the terrestrial magnetic field induced by human activity) are still not clear and call for more fundamental studies.
