| Popis: | A Ce–Bi@CeBiOx/C with core–shell structure has been synthesized by pyrolysis of cerium doped bismuth-based metal–organic frameworks. This novel catalyst exhibits excellent performance for electrochemical CO2 reduction to formate with a maximum faradaic efficiency of 96% and a maximum partial current density of 15.2 mA cm−2, which could be attributed to the synergistic effects of electronic structure modification of Bi as well as the enrichment of oxygen vacancies on catalyst surfaces. |
