dc.description.abstract | It is of tremendous significance to develop effective bifunctional electrocatalysts for electrochemical water-splitting to generate sustainable hydrogen energy. Herein, a facile and scalable strategy is evolved to design N doped bamboo-like carbon nanotube decorated with tri-metal nanoparticles (Fe-Ni-Cr/NC) for overall water-splitting in alkaline electrolyte. Coupling effects between different metals and intimately contact with the carbon matrix endow the obtained nanomaterial possesses splendid catalytic activity and stability for cathodic HER, anodic OER and overall water-splitting in alkaline electrolyte. The obtained Fe-Ni-Cr/NC exhibits the best catalytic performance for HER (284 mV@10 mA cm(-2)) relative to Fe-Cr/NC (368 mV), Ni-Cr/NC (314 mV) and Fe-Ni/NC (324 mV). For OER, a small overpotential of 210 mV is needed to drive 10 mAcm(-2) which is superior to IrO2 (330 mV). Thus, the interactions between different metals act as paramount effects on promoting the catalytic activities. Benefiting from the outstanding catalytic performances for both HER and OER, the designed Fe-Ni-Cr/NC possesses splendid catalytic activity for overall water-splitting with a small potential of 1.64 V to deliver 10 mA cm(-2). Moreover, the obtained nanomaterial also owns remarkable long-term stability in the measured electrolyte. | - |
