Three-dimensional (3D) reduced graphene oxide (rGO)/Ti2CTx MXene hybrid aerogels were effectively prepared by a two-step method involving hydrothermal reaction and freeze-drying. The intimately coupled rGO/Ti2CTx aerogel combined high electrical conductivity, large interlayer spacing, excellent mechanical stability of Ti2CTx, which not only prevents the self-restacking Ti2CTx nanosheets, exposes more active sites exposed, improves volume change during charge/discharge process but also increases accessibility ions promotes rapid transfer ions/electrons. As result, 17.5-2.5 as working electrode electric double layer capacitors delivers specific capacity (107.05 F g-1 at 0.5 A in 1M Na2SO4 electrolyte), rate capability (maintains 30% its initial capacitance 10 g-1, is much better than rGO Ti2CTx), long-term large-current cycle (the remains above 71.1% after 000 cycles 1 g-1). In addition to providing high-performance for supercapacitors, this study proposes an efficient time-saving strategy constructing 3D structures from 2D materials.
