Highlights • A novel NC-Ti 3 C 2 T x hybrid has been synthesized. • NC-Ti 3 C 2 T x hybrid exhibits quick charge/discharge rate up to 3.0 V s−1. • NC-Ti 3 C 2 T x hybrid exhibits higher specific capacitance of 82.8 F g−1 at 1.0 A g−1. • The hybrid exhibits excellent cycling stability (100% retention after 5000 cycles). Abstract The MXenes with excellent chemical and physical properties are novel and promising electrode materials for supercapacitors. However, aggregation and restacking of MXene sheets limit material's electrochemical performance. Here, we report a method to prevent MXene sheets from restacking and significantly improved electrochemical capability of Ti 3 C 2 T x MXene by intercalating with N-doped carbon (NC) introduced from ZIF-8. Ti 3 C 2 T x MXene sheets were prepared by etching Ti 3 AlC 2 powder in HF, then ZIF-8/Ti 3 C 2 T x composite was prepared, followed by annealing in H 2 /Ar atmosphere. Benefited from higher specific surface area and electron conductivity, the obtained NC-Ti 3 C 2 T x hybrid shows the quick charge/discharge rate up to 3.0 V s−1, little IR drop at 50.0 A g−1, higher specific capacitance of 82.8 F g−1 at 1.0 A g−1 (about 210% of the origin), and 100% retention in capacitance after 5000 cycles. This new and effective approach efficiently enhanced the electrochemical performance of Ti 3 C 2 T x MXenes and improved them as one of auspicious electrode materials in future energy storage devices.
