Abstract

A SiO₂@ PPy core/shell structure was synthesized by performing the polymerization of pyrrole monomers around SiO₂ spheres. For the first time, the SiC hollow spheres with a high surface area were prepared from the SiO₂@ PPy with a core/shell structure by using a carbothermal reduction reaction technique. The preparation process and the structures of the products were characterized with XRD, TEM, SEM, N₂ adsorption-desorption isotherms and XPS. The results indicate that β-SiC hollow spheres with a specific surface area of 101.3 m²/g could be prepared from the SiO₂@ PPy with a core/shell structure.
