MXene is a new 2D transition metal carbide possessing metallic conductivity and hydrophilic surfaces. It has drawn widespread attention as a potential material for electrode use. However, the applications of MXene are limited by its property of low electrical capacity. In this paper, a novel MnO 2 /MXene composite is prepared by electrostatic self-assembly. Firstly, delaminated MnO 2 nanosheets are obtained through the intercalation delamination of multilayered H-MnO 2 in a cationic Gemini surfactant (Gem) solution, leading to a positively char...
