Abstract:
Linker-transformation modulation enables one-pot assembly of SUM-70, a stable heterobimetallic MOF integrating Bi38-oxo clusters and CuN4 nodes through synchronized Bi-O/Cu-N coordination. SUM-70 shows broad pH tolerance and selective CO2-to-HCOOH electrocatalysis, achieving 96.21% faradaic efficiency and maintaining FEHCOOH above 95% over 18 h.
