| مستخلص: |
• 2.7 nm NiP amorphous quantum dots were prepared by metal-support interaction. • Fe/N/C support tunes the NiP quantum dots electron structure configuration. • Overpotential of 242 mV at 10 mA cm−2 and Tafel slopes of 47 mV dec−1 are achieved. Amorphous nickel phosphorus (NiP) is regarded as one of the most promising efficient catalysts for oxygen evolution reaction (OER). Here, amorphous NiP quantum dots with a diameter of 2.7 nm were successfully prepared by metal-Fe/N/C support interaction. Owing to the high specific surface areas, the abundant defects caused by N-doping, and the charge transfer between Fe single atoms and NiP, amorphous NiP quantum dots achieve a low overpotential of 242 mV at 10 mA cm−2. This work provides an efficient way to construct amorphous quantum dots by strong metal-support interaction. [ABSTRACT FROM AUTHOR] |
