摘要：

In this work, d-Ti3CN MXene was obtained by selective etching of Al from Ti3AlCN by hydrofluoric acid, and a hydrothermal method was employed to prepare d-Ti3CN/V2O5 hollow spheres. The prepared d-Ti3CN/V2O5 hollow spheres showed enhanced electrochemical properties. V2O5 hollow spheres expanded the distance between d-Ti3CN MXene sheets, leading to fast electron transport and improved electrochemical performance of dTi3CN/V2O5 hollow spheres. A specific capacitance of 340 F g-1 was achieved at 1 A g-1 current density, which is higher than that of d-Ti3CN MXene (321 F g-1) and V2O5 hollow sphere (155 F g-1). The initial capacitance retention is 89 % after 6000 cycles of constant current charge and discharge at the current density of 10 A g-1. In short, d-Ti3CN/V2O5 hollow spheres show excellent supercapacitor performance regarding specific capacitance and stability.
