Facile synthesis of Er-MOF/Fe₂O₃ nanocomposite for oxygen evolution reaction

Currently, energy disasters and environmental contamination are of worldwide concern, and to replace the dependency on fossil fuels, it is required to use a different alternate energy resource. to confirm a green and sustainable future. In the current effort, simple Er-MOF and its nanocomposite (Er-MOF/Fe₂O₃) were manufactured through hydrothermal method which freshly produced on the conducting surface of NF (Nickle Foam) for OER (oxygen evolution reaction) in 1.0 M KOH electrolyte. The synthesized materials were determined through various analytical methods to study the structure, porosity and morphology by using X-ray Diffraction Analysis (XRD), Brunauer Emmet-Teller (BET) and Scanning Electron Microscopy (SEM), and studies, respectively. The water-splitting measurement of the fabricated composite material showed the outstanding oxygen activity for oxygen evolution reaction and observed lower overpotential of 216 mV to achieve a current density of 10 mA/cm², a lower onset potential of 1.43 V through lower Tafel slope of 47 mV/dec. Hence, present effort may present a novel opportunity. avenue for OER.
