英文摘要	In this work, the porous o-(Co,Fe)Se-2/Ti2C MXene composite microspheres have been prepared using a facile and simple strategy via in-situ growth of orthorhombic o-(Co,Fe)Se-2 on few-layered Ti2C MXene and subsequent vacuum calcination. The porous o-(Co,Fe)Se-2/Ti2C composite microspheres exhibits a high re-versible capacity of 286.2 mA h g-1 at a current density of 1 A g(-1). In addition, the assembled asymmetric supercapacitor demonstrates a competitive energy density (68.9 Wh kg(-1) at 800.0 W kg(-1)) and a robust long cycling stability (65.3 % capacitance retention after 10,000 cycles). The excellent electrochemical performance is described to the unique architecture of porous o-(Co,Fe)Se-2/Ti2C microspheres and the synergistic effect of Fe doping and compositing with MXene.
