英文摘要 | Supramolecular pillared oxides M - MnO2 (M Ba2+; Sr2+; ZrO2+) were prepared through the intercalation of M2+ cations into a MnO2 host matrix by the method of ion exchange between the precursor delta-KxMnO2 and the corresponding guest. The materials M-MnO2 crystallize in the hexagonal system, the same structure as the precursor, with a larger interlamellar spacing. In the case of ZrO-MnO2, extended X-ray absorption fine structure (EXAFS) determination indicates that the Zr atom locates between the MnO2 layers forming a stable structure. Compared with the precursor, the cycling property of M-MnO2 was improved distinctly, while the capacity decreased to some degree due to the strong interaction between pillars and the host matrix. Among these pillared materials, ZrO-MnO2 has an advanced reversible capacity of 161.5 mAh center dot g(-1) and improved cycling behavior compared with the precursor. |
