| titleOfInvention | Noble metal nanoparticles/silica nano-space capsule composite material and preparation method thereof |
| abstract | The invention discloses a precious metal nano-particle/silicon dioxide nano-space capsule composite material and a preparation method thereof; the preparation method comprises the following steps: Step 1, dispersing the precious metal nano-particles in water, adding silver nitrate and reacting with a reducing agent to obtain Precious metal/silver core-shell nanoparticle dispersion; step 2, drop the dispersion into a mixed solvent of water/alcohol, add two ligands, surfactant and ammonia water under vigorous stirring, and the two ligands are mercapto groups respectively Carboxylic acid ligand and polyacrylic acid with large molecular weight; step 3, continue to add silicon source and stir to obtain a hollow nanocomposite material in the shape of a space capsule. The preparation method of the invention is simple, the conditions are mild, and the shape is controllable, and the asymmetric sac-like nanostructure with openings on the surface is obtained. |
