Abstract:
Ti 3 C 2 T x , as novel members of the two-dimensional material family, hold great promise for electrochemical energy storage and catalysis, however, the electrochemical performance of Ti 3 C 2 T x is largely limited by the self-restacking of their layers due to van der Waals forces. In this study, we report a high-performance electrode material, Ti 3 C 2 T x supported Fe 3 O 4 nanoplates (denoted as MXene–Fe), synthesized by a simple in situ wet chemistry method in a solvothermal system. The mesoporous MXene–Fe material as a supercapacitor electrode exhibits a high specific capacitance of 368.0 F g −1 at 1.0 A g −1 and long cycling stability with about 81% capacitance retention after 10 000 cycles at 10.0 A g −1 . Moreover, the optimized MXene–Fe also displays high electrocatalytic activity and stability toward the oxygen evolution reaction in alkaline solution (1.0 M KOH) with a low overpotential of 290 mV at 10 mA cm −2 and a small Tafel slope of 65.1 mV dec −1 . This work provides an effective strategy for developing novel Ti 3 C 2 T x -based functional materials with outstanding electrochemical performance for supercapacitors and electrocatalysis.
