Conversion of CO₂ into specific light olefins with high selectivity is a challenge. In this issue of Chem, Fan and co-workers propose an ethanol-intermediate route with the design of a new catalyst: Cr₂O₃(SG)/H-SAPO-34. The C₂⁼–C₄⁼ selectivity can reach 95.7%, and ethene accounts for 74% of light olefins in CO₂ hydrogenation.
