2D Carbon-Supported Platinum Catalysts for Hydrosilylation Reactions

2D carbon structures were prepared by carbonization of biopolymers (starch) via self-propagating high-temperature synthesis process. Electron microscopic, Raman spectroscopic, and X-ray diffraction examinations showed that the structure of the resultant particles corresponded to graphene nanoplatelets. Based on the Raman spectroscopy data, the average number of graphene layers in a graphene nanoplatelets particle was estimated at 2-5. The graphene nanoplatelets synthesized were applied as a support of a platinum-based catalyst (Speier's catalyst). The resultant supported catalyst was successfully used in the hydrosilylation of 1-hexene with methyldichlorosilane and then separated from the reaction products and reused. The catalytic activity of the supported catalyst was maintained for 4 months.
