Abstract
AbstractA novel layered nanocomposite was fabricated by the self‐assembly of TiNbO5‐nanosheets and 5,10,15,20‐tetrakis(N‐methylpyridinium‐4‐yl)porphyrinatocobalt(III) (CoTMPyP). The product was characterized by a variety of analytical techniques such as XRD, EDX, Zeta potential, AFM, UV‐vis, IR and SEM, the guest species were intercalated into the interlayer gallery of KTiNbO5 successfully. The electrochemical property of TiNbO5‐CoTMPyP as an electrode modifying material was examined by cyclic voltammetry test in PBS solution (pH=7), and the hybrid exhibited excellent electrocatalytical property towards oxygen reduction with the peak potential shifting from −0.703 V (bare GCE) to −0.278 V (modified electrode). The result also indicated that the oxygen molecule was reduced to H2O2 by a two‐electron process.
