Construction of Mo2N nanoparticles embedded in N, O-doped carbon sheets and its supercapacitive behaviors
Source abstract
Abstract
The Mo 2 N is a promising candidate electrode material for supercapacitors. The molybdenum nitride nanoparticles embedded in N, O co-doped carbon sheets composite (Mo 2NNPs/NOCS) is fabricated via Mo 2 N nanoparticles in situ growth on the surface of self- sacrifice C 3N 4. The results show that small size of Mo 2 N nanoparticles ranged from 1.2 to 1.5 nm are distributed uniformly and embedded in the surface of carbon nanosheet materials. The effects of temperature and ratio of ammonium molybdate tetrahydrate to C 3N 4 on electrochemical performance are investigated in detail. The maximum specific capacitance can achieve 294 F g −1 at 0.5 A g −1 after optimization. Further, the supercapacitor device is assembled with a commercial activated carbon YP50 as a positive electrode in an acid electrolyte, delivering a high energy density of 13.6 Wh kg −1.
