| titleOfInvention | Preparation method of water-soluble silver sulfide nanoshell |
| abstract | The invention belongs to the field of nano material preparation, and particularly relates to a preparation method of a water-soluble silver sulfide nanoshell. The preparation method comprises the following steps: dissolving protein in water, and adding hydrochloric acid to adjust the pH value to acidity to obtain a solution A; adding a silver nitrate solution into the solution A, and reacting under a stirring condition to form a protein-silver ion compound to obtain a solution B; and (3) rapidly adding the sulfur solution into the solution B at room temperature, and stirring to form the silver sulfide nanoshell. The invention utilizes hydrochloric acid to adjust protein solution to acidity, under the acidic condition, silver ions and protein firstly form protein-silver ion compound, and then a sulfur source is added to generate silver sulfide nanoshell; the silver sulfide nanoshell is different from silver sulfide quantum dots, is good in crystallinity, uniform and stable in dispersion, and has a good application prospect in solar cells, catalysis, organism photothermal imaging and treatment, and drug loading. |
