Microwave synthesis of titanium-containing carbon nanosheet over mesostructured cellular foam and the catalytic application

摘要: Abstract Titanium-containing carbon nanosheets have been prepared from graphite powder, titanocene dichloride, pyrrole and other components by using mesostructured cellular foam (MCF) as template under microwave irradiation. Characterizations reveal the present similar composition, functional group thickness classical graphene oxide, but they are probably formed stitching of tiny fibers those grown pores MCF. Meanwhile, titanium oxides appear on nanosheets, making a new catalytic system. In oxidation alkenes, synthetic materials provide satisfactory conversions promising stereoselectivities. Moreover, various oxidized products obtained key intermediates for synthesis high-value-added chemicals. On hand, encouraging chiral inductions realized in diethylzinc addition to benzaldehyde. Catalytic results also propose synergy MCF with attached additive induction. This work not only provides method produce two-dimensional materials, shows their potentials transformation hydrocarbons, which would contribute design heterogeneous catalysts.
