Mesoporous silica vesicles have been prepared by an ultrasound‐mediated supramolecular templating technique using cetyltrimethylammonium bromide as the surfactant. Cooperative assembly of the surfactant and silicate species near the air–water interface of the cavitating bubbles results in a vesicular morphology. The vesicles are thermally stable, possessing wormhole‐like mesopores and a high surface area.
