▎ 摘　　要

A novel iron(II) tetraaminophthalocyanine graphene (FeTAPc-Gr) micro/nanocomposite as a non-noble catalyst for oxygen reduction reaction (ORR) was prepared by amidation of the carboxyl groups at the edge of graphene nanosheets with amino group of FeTAPc, meanwhile, we found that FeTAPc moieties could assemble to nanoparticles on graphene sheet trough pi-pi interaction in our experiment condition. FePc-Gr composite was characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). The electrocatalytic performance for ORR was assessed by cyclic voltammetry (CV) and linear sweep voltammetry (LSV) methods. A well-defined characteristic ORR peak, centered at -0.148 V vs. SCE was observed on FeTAPc-Gr composite catalyst, whereas the peak potential on commercial Pt/C was -0.199 V vs. SCE at the same condition. The resulting product exhibits excellent ORR activity, super tolerance to methanol crossover and good stability, which lead to the invention of a new non-noble catalyst for ORR in fuel cell.
