metallic naonoparticle bound to the surface of mesoporous silica support having ordered 3-D pore structure and method for preparation thereof

摘要

The present invention includes the steps of: (a) introducing multiple amine groups on the surface of the mesoporous silica support having an ordered three-dimensional pore structure; (b) introducing metal ions by contacting the mesoporous silica support having a regular three-dimensional pore structure in which the multiple amine groups are immobilized with an active metal precursor; And (c) reducing the adsorbed metal ions to form metal nanoparticles, comprising a mesoporous silica support having a regular three-dimensional pore structure, and metal nanoparticles fixed to the inner and outer surfaces of the pores thereof. It relates to a method of manufacturing a composite containing and metal nanoparticles fixed on a mesoporous silica support having a three-dimensional pore structure thus prepared, the process is simplified, and the surface area is increased by the use of a silica support having a three-dimensional shape. , It can be applied as a heterogeneous catalyst.
