Facile synthesis of MoO2/CNTs composites for high-performance supercapacitor electrodes
Source abstract
Abstract
Abstract A simple one-pot hydrothermal method to synthesize MoO 2 /CNTs nanocomposites on nickel foam substrate for supercapacitor electrode was developed. Compared to pure MoO 2 nanoparticles, the MoO 2 /CNTs nanocomposites show better electrochemical performance. The specific capacitance values of pristine MoO 2 , MoO 2 /CNTs (5 wt%) composite and MoO 2 /CNTs (10 wt%) composite were 327.4, 467.4 F g −1 and 424.7 F g −1 of at a current density of 1 A g −1 , respectively. Especially, MoO 2 /CNTs (5 wt%) composite exhibits good rate capability and excellent cycle densities, remaining at 92.8% of the initial specific capacitance value even after 3000 cycles at 5 A g −1 . The enhanced electrochemical behaviors are mainly due to the synergistic effect of combining MoO 2 nanoparticles and CNTs. MoO 2 nanoparticles can provide higher specific capacitance, while CNTs improve the electrical conductivity and structural stability of the composite. Such nanocomposite with high performance may be used as a promising material for electrochemical supercapacitor.
