High-Yield Synthesis of Periodic Mesoporous Silica Rods and Their Replication to Mesoporous Carbon Rods

Ordered mesoporous carbon rods have been obtained in high yield using silica rods as templates. The inorganic salts that are used for the synthesis of the silica templates control the morphology and adjust the wall structure of the mesoporous silica materials and thus of the final carbon rods. The Figure shows a TEM image of a carbon sample synthesized using SBA-15-100 silica as a template.
