Recent reports on graphene-nanomaterial composites as active materials for photocatalysis and energy storage device highlight the synergistic effects between graphene and nanomaterial due to graphene’s fast carrier mobility, high conductivity and large surface area. However, despite importance of morphology and size distribution of nanomaterial in electrochemistry, the precise control of its properties has not been widely reported yet. In our research, we explored synthesis method of the vertically aligned mesoporous silica-graphene composite as template for nanomaterial-graphene composite. The hexagonally ordered porous silica structure was formed on the graphene oxide via self-assembly of the graphene, a silica precursor and a cationic surfactant. We anticipate that the mesoporous silica-graphene composite is very useful to guide the synthesis of various nanomaterials on the graphene and it is obtained as a bulk type which is essential to utilize it in industrial level. |
