Abstract: A fast and mild method was developed to prepare Co-MOF-74 nanoparticles with high crystallinity and uniform morphology at room temperature for efficient oxygen evolution reaction (OER) in alkaline media. Compared with the conventional hydrothermal route, the time required for synthesis was greatly reduced after introducing triethylamine:Co-MOF-74 nanoparticles (about 20 nm) could be readily available by stirring at room temperature for only 2 h. The nano-electrocatalyst exhibited a larger specific surface area (760 m2·g-1), excellent activities and stability for OER with an overpotential of 275 mV to achieve a current density of 10 mA·cm-2.
