Advanced MXene/MoS2 nanoparticles with polyethyleneimine intercalation for asymmetric energy storage applications
Titanium carbide (Ti 3 C 2), a two-dimensional material known as MXene, is a promising electrode material for supercapacitors. Herein, MXene was synthesized by etching the Ti₃AlC₂ MAX phase, followed by intercalation with polyethyleneimine (PEI). Additionally, the precursor MoS 2 was injected into MXenes at an early stage. The MXene and MoS 2/MXene@ PEI materials were characterized using X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and BET analysis techniques. Several techniques were employed to assess the electrochemical properties of MXene, MoS 2/MXene, and MoS 2/MXene@ PEI heterostructures. Based on the results of the electrochemical experiments, it has been demonstrated that the MoS 2/MXene@ PEI NCs electrodes have the potential to achieve a maximum specific capacitance of 632 F g− 1. Additionally, the discharge current density of these electrodes is 1 A g− 1. Additionally, MoS 2 has been demonstrated to reduce the charge transfer resistance of MoS 2/MXene@ PEI, as indicated by the results of electrochemical impedance testing. The electrochemical performance of MoS 2/MXene@ PEI NCs was remarkable, particularly in terms of reversibility, cycle stability, and rate performance. The research concludes that MoS 2/MXene@ PEI is an excellent candidate for use as an electrode in supercapacitors.
