| titleOfInvention | Preparation method of silica @ noble metal nano-composite microspheres |
| abstract | The invention discloses a preparation method of silica @ noble metal nano-composite microspheres. The method comprises the following steps: 1) preparing silica nano microspheres; 2) dispersing the nano microspheres into tri-distilled water, and adding a sodium chloride water solution of polyelectrolyte to obtain polyelectrolyte-modified silica nano microspheres; 3) dispersing the nano microspheres into the tri-distilled water, and dropwise adding a noble metal salt water solution to obtain polyelectrolyte-modified silica nano microspheres stained with noble metal ions; 4) dispersing the silica nano microspheres into the tri-distilled water, and dropwise adding a sodium borohydride water solution to obtain the silica @ noble metal nano-composite microspheres. According to the preparation method, water is taken as a medium under the reaction condition at a room temperature of 25 DEG C; an organic solvent is not required; complicated and tedious modifying processes are not required; the silica @ noble metal nano-composite microspheres with high dispersity and good stability can be rapidly prepared; the method is simple and feasible, good in repeatability, and simple in reaction device; large-scale production can be achieved according to the production requirements. |
