Procedure

In addition to hydrogenation of a series of alkenes, the nanospheres are proved to catalyze the Heck coupling reaction between styrene and iodobenzene forming trans-stilbene with ˜100% yield in 12 hours (FIG. 21). Furthermore, the catalyst showed good recyclability in the Heck coupling reaction as well.
