Active-site stabilized Bi metal–organic framework-based catalyst for highly active and selective electroreduction of CO2 to formate over a wide potential window

The fabricated bismuth-terephthalate framework (Bi-BDC) showed a high efficiency for electroreduction of CO 2 to formate over a wide potential window. Bi-BDC gradually evolved to Bi 2 O 2 CO 3 after a long-term reaction but remained an excellent activity.
