  • Hollow-structured mesoporous silica material and preparation process
    Publication number: 20050244322
    Abstract: A hollow-structured mesoporous silica material composed of hollow silica particles that have a shell having radial-arrayed channels, and a process for its preparation. The thin-shell type of mesoporous materials with different morphologies are prepared by growing and synthesizing mesoporous silica on the surface of calcium carbonate nanoparticles with different shapes as inorganic templates, and then removing the inorganic templates. The hollow-structure mesoporous silica material can be used in many fields such as the preparation of catalyst, pesticide and optical fiber.
