Description
Summary:The innovation in highly efficient, stable, and economical bifunctional overall water-splitting electrocatalysts is critical in developing sustainable energy, but it remains challenging. In this research, we have developed an unsophisticated method to synthesize hybrid nanoparticles (FeN0.023/Mo2C/C) uniformly dispersed in nitrogen-doped carbon nanosheets. The two active components FeN0.023 and Mo2C are coupled to form an FeN0.023/Mo2C/C heterostructure being a highly efficient electrocatalyst, which gives low overpotentials of 227/76 mV for OER/HER at 10 mA cm–2 current density. The alkaline-electrolyzer with FeN0.023/Mo2C/C as the anode–cathode catalyst needs merely 1.55 V to reach 10 mA cm–2 and can maintain a stable state for a minimum of 10 h. This research gives a simple effective resolution in designing affordable and useful overall water-splitting electrocatalysts.
