摘要

Herein, a hybrid material composed of doped Polypyrrole (PPy) on two-dimensional Ti3C2Tx MXene surface is presented as a high-performance electrochemical supercapacitor electrode. PPy is deposited on the synthesized Ti3C2Tx surfaces employing in-situ chemical polymerization to fabricate PPy @Ti3C2Tx electrodes. The improvement of electrochemical performance of PPy@Ti3C2Tx is investigated by introducing two anionic dopants: alpha-naphthalene sulfonic acid (alpha-NSA) and a mixture of anthraquinone-2-sulfonic acid sodium salt monohydrate/5-sulfosalicylic acid dihydrate (AQSANa,SSCA). While the maximum specific capacitances of the Ti3C2Tx, PPy@Ti3C2Tx and AQSANa,SSCA doped PPy@Ti3C2Tx are 232.2, 154.4, 105.9 F g(-1) at the scan rate of 5 mV s(-1), respectively; they retain less than 70% of their initial capacitance over 2000 cycles. alpha-NSA doped PPy@Ti3C2Tx exhibits the best electrochemical performance with the highest specific capacitance (347.6 F g(-1)) and significantly more capacitance retention (90% over more than 4000 cycles). This notable improvement proposes alpha-NSA doped PPy @Ti3C2Tx MXene nano structured material as a high-performance supercapacitor electrode.
