Selective and Efficient Photocatalytic Conversion of CO2 with Ultrathin Nanosheets
Prof. Doh Chang Lee’s group has developed a novel photocatalyst based on ultrathin CdS nanosheets for selective and efficient light-driven conversion of CO2 into CO. Surface engineering at atomic precision on CdS nanosheets enabled spatial separation of the reductive active sites and the oxidative active sites to designated facets. The facet-resolved redox-active sites favored efficient charge separation in the CdS nanosheets under light, leading to two-orders-of-magnitude increase in conversion rate of CO2-to-CO. ...read more

Energy-Saving CO2 Hydrogenation Using Light
Light-assisted CO2 hydrogenation produced methane on a Ru/SiO2 catalyst. By using both light and heat as an energy source, the total energy required for CO2 conversion could be reduced to 37%. The chemical reaction can be easily initiated or terminated by simply turning on or off the light....read more
