METHOD FOR PRODUCING HOLLOW NANOPARTICLE COMPRISING MESOPOROUS SILICA SHELL

摘要

PROBLEM TO BE SOLVED: To provide a method for easily producing hollow nanoparticles comprising a silica shell of a mesoporous structure having an average pore diameter of 1-10 nm with high production efficiency.

SOLUTION: An aqueous surfactant solution is mixed with calcium carbonate shape-controlled to be nanosize to form a surfactant micelle structure on the calcium carbonate surface, and hollow nanoparticles comprising a silica shell of a mesoporous structure corresponding to the micelle structure are produced by a reaction of a silicon alkoxide.
