Abstract : A three-dimensional carbon nanotube-silica coated reduced graphene oxide hybrid (CNT-SiO2@RGO) was synthesized by floating-catalyst chemical vapor deposition (CVD), in which ferrocene was used as catalyst precursor and acetylene as carbon source. Graphene oxide (GO) was selected as the template and was pre-treated by tetraethyl orthosilicate (TEOS) to deposit a SiO2 layer on both sides of the platelet surface. The obtained hybrid has a uniform structure consisting of a platelet sandwiched by vertically aligned CNTs. The CNT length can be well controlled by the variation of growth time.
