Selective Carbon Dioxide Hydrogenation to Olefin-Rich Hydrocarbons by Cu/FeOx Nanoarchitectures Under Atmospheric Pressure.

ABSTRACT: The conversion of carbon dioxide into fuels and fine chemicals is a highly desirable route for mitigating flue gas emissions. However, achieving selectivity toward olefins remains challenging and typically requires high temperatures and pressures. Herein, we address this challenge using 12 nm copper nanoparticles supported on FeOx micro-rods, which promote the selective hydrogenation of CO₂ to light olefins (C₂-C₄) under atmospheric pressure. This catalyst achieves up to 27% conversion and 52% selectivity toward C₂-C₄ olefins, along with the production of C₂-C₄ paraffins, C₅+ hydrocarbons (with all C₁₊ products totalling to up to about 75%), and methane, while suppressing CO formation to just
