Catalytic hydrogenation of carbon dioxide into chemicals and fuels has moved into the spotlight in the recent carbon-neutral age. However, this sustainable process is still a low efficiency one due to the limitations of the catalyst materials. Herein, we designed a highly active CuNaFe catalyst with a self-made physical sputtering method for CO2hydrogenation. The total space time yield (STY) rate of high-value olefin and ethanol can reach as high as 833 mg·g-1·h-1under a mild condition of 310 °C and 3 MPa, which ranks as one of the top performances among related studies. The characterizations demonstrate that the surface of highly dispersed Cu nanoparticles coupled with surrounding Na modified Fe5C2creates a well-matched process of C-O activation, C-C coupling, and C-O insertion. These findings provide a new and general strategy to fabricate a high-efficiency catalyst for direct CO2hydrogenation into useful chemicals.
