Multiscale structural regulation of metal-organic framework nanofilm arrays for efficient oxygen evolution reaction.

Novel MOF nanofilm arrays (NiCoBDC-Fc) were grown on Ni foam via a multiscale structural regulation strategy. The introduction of metal doping and defects regulated the morphology of NiBDC for increasing the exposure of electrochemically active sites and adjusted the electronic structure of the Ni active center, which enhanced the OER performance of NiCoBDC-Fc/NF.
