Abstract

Addressing energy and environmental issues, developing highly efficient, durable, and earth-abundant, electrocatalysts are crucial in oxygen evolution reaction (OER) for energy conversion and storage. Extensive research about the metal-organic framework (MOF) derived layered double hydroxides (LDH) and carbon-based electrocatalysts have been devoted, despite the exceptional performance in OER, yet the limited exposed active sites remain a challenge. Therefore, we reported a novel heteroatom-doped graphene quantum dots (GQDs) incorporated into MOF-derived NiFe-LDH. Taking advantage of abundant active and edge sites of GQDs and modifying the surface chemistry by chemical doping with foreign atoms, the designed heteroatom-doped GQDs/MOF-derived LDH exhibited superior catalytic performance low overpotential of 251 mV at a current density of 100 mA cm -2 in alkaline media. Our result confirmed the synergistic effect between the doped heteroatom and the uttermost exposure of heteroatom-doped GQDs/MOF-derived LDH’s active sites on its surface, providing swift reactant’s transportation and adequate contact for improving the OER performance.
