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 (delta-MnO2 nanofragments, alpha-MnO2 nanorods, alpha-MnO2 nanoflowers and alpha-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@alpha-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.
