英文摘要Developing copper-free catalysts for CO(2)conversion into hydrocarbons and oxygenates is highly desirable for electrochemical CO(2)reduction reaction (CO2RR). Herein, we report a cobalt phthalocyanine (CoPc) and zinc-nitrogen-carbon (Zn-N-C) tandem catalyst for CO2RR to CH4. This tandem catalyst shows a more than 100 times enhancement of the CH4/CO production rate ratio compared with CoPc or Zn-N-C alone. Density functional theory (DFT) calculations and electrochemical CO reduction reaction results suggest that CO(2)is first reduced into CO over CoPc and then CO diffuses onto Zn-N-C for further conversion into CH(4)over Zn-N(4)site, decoupling complicated CO2RR pathway on single active site into a two-step tandem reaction. Moreover, mechanistic analysis indicates that CoPc not only generates CO but also enhances the availability of *H over adjacent N sites in Zn-N-4, which is the key to achieve the high CH(4)production rate and understand the intriguing electrocatalytic behavior which is distinctive to copper-based tandem catalysts.
