Abstract
The two-dimensional (2D) Fe–Ni–Co-MOF is synthesized using a simple double ligand strategy at room temperature. The surface reconstruction process transforms it into a crystalline–amorphous heterojunction composed of polycrystalline metal (oxy)hydroxide (MOOH) and amorphous metal oxides/hydroxides with terephthalic acid (TPA) by coordination covalent bonding. In situ Raman spectroscopy discloses the dynamic structure conversion. Density functional theory (DFT), Fourier transform infrared spectroscopy (FTIR), and solid-state nuclear magnetic resonance (SSNMR) reveal the induction of the ligand defects on surface reconstruction and the enhancing effect of TPA on the oxygen evolution reaction (OER) performance…
