Low-Temperature Catalytic Graphitization of phenolic resin using a co-ni bimetallc catalyst

摘要

Using a Co-Ni bimetallic catalyst we investigated the catalytic graphitization of phenolic resin at 400, 600, 800, and 1000 °C under an Ar atmosphere. The structure and morphology of the pyrolyzed resin were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results show that the optimum catalytic graphitization temperature of phenolic resin is 800 °C, both carbon nanotubes and carbon onions are formed in the final products.
