摘      要：A porous carbon spheres@MnO2 composite is prepared and used as the electrosorption electrode. The MnO2 nanoparticles are evenly distributed on the porous carbon spheres. The as-prepared composite possesses high specific surface area of 258.6 m2·g -1. Its electrochemical evaluations confirm that the composite has high specific capacitance of 175 Fog-1 at a current density of 1 A·g -1 in 0.5 mol·L-1 NaC1 aqueous solution, and shows good conductivity and excellent cycling performance. Electrosorption capacity for the porous carbon spheres@MnO2 composite is 6.28 mg·g-1. Moreover, the composite electrode exhibits excellent recyclability with an efficient regeneration process.
