HOLLOW SILICA NANOPARTICLE COMPLEXED WITH NANOPARTICLE AND PRODUCTION METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a complexed hollow nanoparticle composed of a silica shell on arbitrary sites of which a metal nanoparticle or a metal oxide nanoparticle is carried; and a method for stably supplying the complexed hollow nanoparticle while maintaining dispersibility of the nanoparticle, and retaining the characteristic possessed by the hollow particle.;SOLUTION: The production method of the complexed hollow nanoparticle comprises: producing a hollow nanoparticle composed of silica shells with different average pore diameters; and a metal or a metal oxide is selectively carried on at least one site among a silica shell outer surface, inside silica shell or a silica shell inner surface.;COPYRIGHT: (C)2013,JPO&INPIT
