【 摘 要 】

A new nanocomposite of manganese porphyrin/titanate (MnPP-Ti4O9) was prepared successfully by delamination/reassembling (DR) method, with layered titanate as the host material, manganese porphyrin (MnPP) as the guest material. The microstucture of MnPP-Ti4O9was characterized by XRD, UV-Vis, SEM and TEM. MnPP molecules were closely tilted against the host nanosheets at an inclined angle of 42.7°, by simple geometric calculation. The electrochemical performance of the nanocomposite was measured using cyclic voltammetry (CV). It was found that MnPP-Ti4O9modified glassy carbon electrode (MTGCE) showed desired electrochemical performance and good catalytic activity for oxygen reduction.
