A hybrid material of carbon nanotubes (CNTs) and Mn-based metal organic frameworks (Mn-MOF) was synthesized and used as a Mn-based supercapacitor electrode material. The incorporation of CNTs into Mn-MOF led to an inherent improvement in conductivity and an intrinsic increase in specific capacitance (from 43.2 F g(-1) for pure Mn-MOF to 203.1 F g(-1) for CNTs@Mn-MOF). Furthermore, the symmetrical supercapacitor based on the CNTs@Mn-MOF exhibited excellent power density and outstanding stability even after 3000 cycles with 88% retention of the initial capacitance. This research exploited a new direction for developing Mn-based supercapacitor materials and provided an effective method to improve capacitive performance of MOFs materials.
