Self-Assembly Vertical Graphene-Based MoO(3) Nanosheets for High Performance Supercapacitors
Supercapacitors have been extensively studied due to their advantages of fast-charging and discharging, high-power density, long-cycling life, low cost, etc. Exploring novel nanomaterial schemes for high-performance electrode materials is of great significance. Herein, a strategy to combine vertical...

description | Supercapacitors have been extensively studied due to their advantages of fast-charging and discharging, high-power density, long-cycling life, low cost, etc. Exploring novel nanomaterial schemes for high-performance electrode materials is of great significance. Herein, a strategy to combine vertical graphene (VG) with MoO(3) nanosheets to form a composite VG/MoO(3) nanostructure is proposed. VGs as transition layers supply rich active sites for the growth of MoO(3) nanosheets with increasing specific surface areas. The VG transition layer further improves the electric contact and adhesion of the MoO(3) electrode, simultaneously stabilizing its volume and crystal structure during repeated redox reactions. Thus, the prepared VG/MoO(3) nanosheets have been demonstrated to exhibit excellent electrochemical properties, such as high reversible capacitance, better cycling performance, and high-rate capability. |
