摘要：

Iron (II) phthalocyanine (FePc) nanoclusters were synthesized by solvent evaporation with poly(diallyldimethlammonium chloride) as a stabilizer. Combining FePc nanoclusters with graphene (GR), the FePc-GR sandwich composite was produced. Morphologies of the resulted FePc-GR composite were characterized by field emission scanning electron microscopy. It was found that the FePc-GR composite exhibited sandwich structure, and the FePc nanoclusters (similar to 500 nm) consisted of small nanoparticles were uniformly distributed between GR sheets. Electrochemical and electrocatalytical properties of the FePc-GR composite were studied by cyclic voltammetry and linear sweep voltammetry methods. Compared with the pure FePc nanoclusters or GR, the FePc-GR composite showed improved electrocatalytical performance towards oxygen reduction reaction (ORR). The electrocatalytical performance of FePc-GR composite was related to the ratio of FePc nanoclusters and GR. It was observed that the FePc-GR composite showed the highest current density when the volume ratio of FePc nanoclusters to GR was 2:1. The electron transfer number of the FePc-GR composite was 4.05, indicating the direct four electron process for the ORR. In addition, the FePc-GR composite also exhibited good stability and excellent resistance to methanol compared with the commercial 20% Pt/C catalyst. [GRAPHICS] .
