Ir-Doped Ni-based metal–organic framework ultrathin nanosheets on Ni foam for enhanced urea electro-oxidation

TED MOF, BDC = 1,4-benzenedicarboxylic acid, TED = triethylenediamine) ultrathin nanosheets grown on a nickel foam substrate (NiIr-MOF/NF) were synthesized by a facile solvothermal method. The as-synthesized NiIr-MOF/NF composite electrode could bring about increased electrochemical active area, accelerated electron transport capability as well as improved stability, which facilitate the urea oxidation reaction (UOR) electrocatalysis.
