Abstract
Carbon sphere with well mesoporous structure, relatively high BET surface area (~294 m2/g) and uniform pore size (~3.8 nm) was synthesized by hard template method. SiO2 nanoparticles were used as the template, and were introduced during the polymerization of 3-aminophenol and formaldehyde. The structure and morphology of the as-prepared mesoporous carbon sphere were characterized by transmission electron microscope (TEM), X-ray diffraction (XRD), and N2 sorption. Using this mesoporous carbon sphere as carrier to support palladium nanoparticles, we tested its catalytic activity in the reaction of iodobenzene and phenylboronic acid. The result showed that this Pd/mesoporous carbon composite has good catalytic activity.
