Hollow nano rattle particle for preparing less-noble metal nanoparticle and less-noble metal nanoparticle prepared thereby

摘要

The present invention is seeded with a hollow nano-particles and rattle it suitable for the production of nanoparticles as the base metal or its alloy as a base material - a method of producing nanoparticles according to engineering (seed-engineering). Nano rattle particles comprising porous silica nano shell and gold nanocrystals trapped in the pores of the pupil of the present invention can be manufactured simply and easily by using the hybrid nanocrystals, nickel as well as alloys with nickel and other metals a base metal made of nanocrystalline acts as a template for the synthesis and can be used as a nano-reactor for the production of nanoparticles comprising a metal core and a variety of porous silica kkeopjilreul of a predetermined size is manufactured nanoparticles may be modified after addition. In addition, the nanoparticles comprising a base metal core and a porous silica shell of the present invention is to produce a stable colloid in an aqueous medium, and stable in extreme conditions, there is a reactive molecule to the active metal core can be easily accessible catalysts and biosensors It can be effectively used as a.;
