Coal Tar Pitch-Based Porous Carbon Loaded MoS₂ and Its Application in Supercapacitors.

ABSTRACT: In this paper, with coal tar pitch as the carbon source, porous carbon (PC) was prepared by one-step carbonization. To improve the energy density of coal tar pitch-based porous carbon, MoS₂@PC was prepared by a hydrothermal method on a PC substrate. The effect of MoS₂ loading on the structure and electrochemical properties of the sample was studied. The results show that the specific surface area of the MoS₂@PC-0.3 synthesized is 3053 m² g^-1, and the large specific surface area provides sufficient attachment sites for the storage of electrolyte ions. In the three-electrode system, the specific capacitance of MoS₂@PC-0.3 at 0.5 A g^-1 is 422.5 F g^-1, and the magnification performance is 57.3% at 20 A g
