    Abstract

    Ti3C2Tx@MnO2 composites with different morphologies were prepared by liquid-phase coprecipitation and hydrothermal method using Ti3C2Tx@PDA as matrix, KMnO4 as manganese source, CTAB or PEG as surfactant. Effect of MnO2 morphology (δ-MnO2 nanofragments, α-MnO2 nanorods, α-MnO2 nanoflowers and α-MnO2 nanowires) on phase structure and electrochemical performance of Ti3C2Tx was analyzed by FE-SEM, XRD, Raman, FT-IR, BET, and electrochemical measurements. The results show that Ti3C2Tx@α-MnO2 nanowires possesses better comprehensive electrochemical properties (340.9 F·g -1 at 2 mV·s -1), nearly 2.5 times higher than using CTAB, and smaller charge transfer resistance, as well as excellent cycle stability.
