Graphite oxide-supported Karstedt catalyst for the hydrosilylation of olefins with triethoxysilane

• Graphite oxide was introduced as a support for the immobilization of Karstedt catalyst.
• GO-Karstedt catalyst was active for hydrosilylation of olefins with triethoxysilane.
• GO-Karstedt catalyst could be reused several times without losing its activity.

A graphite oxide-supported Karstedt heterogeneous catalyst was synthesized from vinyltriethoxysilane via immobilization on graphite oxide, followed by reacting with chloroplatinic acid. The samples were characterized by FT-IR, TGA, ICP-AES, XRD and TEM techniques. The catalyst was active for hydrosilylation of olefins with triethoxysilane and showed good recoverability without significant loss in activity and selectivity within successive runs.
