Synthesis of chemically modulated 2D titanium carbides for energy storage materials |
| 초록 |
Low dimensional carbon-based porous materials, carbon nanotubes (1D, CNTs), graphene (2D) and recently, transition metal carbides or nitrides, 2D MXene phases, are emerging as a group of materials showing great promise in energy storage electrodes due to their physical, electrical and chemical properties, stability and transformable structure. The electrochemical characteristics of Ti3C2Tx for supercapacitor electrodes, one of 2D MXene phases, in basic electrolyte is reported. To demonstrate the effect of surface modification on electrochemical performance, surface of Ti3C2Tx, was manipulated by electride salt which generated from alkali metal based basic medium. Electrochemical analysis indicating an improved in capacitance and stability during charging/discharging. It can be described that improving the electrochemical performance was introduced by chemcally modulated surface of Ti3C2Tx. A high capacitance of 395 F/cm3 at 2 A/g was obtained from surface modified Ti3C2Tx which was treated with electride salt. This study note that the behavior of electrode materials from the large family of 2D Mxene can be tuned by suitable modification of their surface chemistry |
