HOLLOW CORE WITH MESOPOROUS SHELL CAPSULE STRUCTURE CONTAINING METAL NANO-PARTICLES HAVING DIAMETERS OF 0.5-50 NANOMETERS WITHIN HOLLOW CORE HAVING DIAMETER OF 30-2,000 NANOMETERS METHOD FOR PREPARING THEREOF

摘要

PURPOSE: To provide a hollow core with mesoporous shell capsule structure containing nano-particles within hollow core, of which a size of macro-pore, a thickness of a shell, a size of meso-pore, and a size of a metal nano-particle are easily controlled, and a method for preparing thereof. CONSTITUTION: The method comprises the steps of: (a) synthesizing metal nano-particles; (b) coating the surface of the synthesized metal nano-particles with silica to prepare M$À silica containing the metal nano-particles therein; (c) forming mesoporous shell on the outside of the M$À silica to prepare solid core with mesoporous shell(SCMS) silica particles; (d) injecting polymer precursor and polymerization initiator into meso pores of the SCMS silica particles to prepare polymer-M$À silica complex; and (e) removing silica from the polymer-M$À silica complex to prepare hollow core with mesoporous shell containing metal nano-particles in hollow core.
