N-Donor flexible ligands for constructing polyoxometalate-based metal–organic frameworks as multifunctional electrocatalysts

Two POMOFs, CUST-631 and CUST-632 , were synthesized by a hydrothermal method and then were directly prepared as electrode materials to explore the electrocatalytic properties for reduction of BrO 3 − and NO 2 − ions and oxidation properties towards AA.
