Fluorinated‐Surfactant‐Templated Synthesis of Hollow Silica Particles with a Single Layer of Mesopores in Their Shells

Hollow silica particles with mesoporous walls (see Figure) are synthesized from solution by co-assembly of silica with cationic fluorinated surfactants. The particles resemble vesicles, but retain wall patterns, indicating that they do not form from silica-coated bilayers but by the co-assembly of silica with micelles. Stronger shearing during synthesis causes the particles to aggregate into elongated particles with multiple hollow chambers.
