Abstract
Mesoporous activated carbon decorated with MnO (MnO/MAC hybrid) was prepared by pyrolysing Mn(CH3COO)2 adsorbed MAC. XRD result proves that typical MnO crystals exist in the MnO/MAC hybrid. The SEM analysis indicates that a lot of pores on the surface of MAC have been filled by MnO. BET result reveals that some pores of MAC are filled by MnO and the MnO/MAC hybrid is a typical mesoporous material. This novel structure ensures the hybrid possesses excellent electrochemical performance. MnO/MAC hybrid delivers a high initial discharge capacity of 1086.1 mAh g−1 and a reversible charge capacity of 600.6 mAh g−1. In addition, MnO/MAC hybrid also exhibits excellent rate performance and cycling performance.
