Sammanfattning

The present disclosure relates to mesoporous silica wrapped nanoparticle composite nanomaterial, preparation method thereof, and use thereof. In the present disclosure, a nanoparticle is dispersed in an aqueous ethanol solution. Then, ammonia water is added to adjust the pH. After that, cetyltrimethylammonium bromide in an aqueous ethanol solution is added dropwise, and ultrasound is continued, before tetraethyl orthosilicate is added dropwise. The mixture is purified to produce a composite nanomaterial that is stable, controllable, and consistent in size; the shell of the composite nanomaterial is mesoporous silica, the core of the composite nanomaterial is a nanoparticle. Dual-core or triple-core nanoparticles of different kinds/functions can be wrapped into a single mesoporous silica shell to achieve multi-core wrapping. The method is universal and may be used to wrap various nanometers. The preparation procedure is environmentally friendly, efficient, and may be carried out at room temperature.
