Porous metal oxide particles and their methods of synthesis |
摘要 |
Methods are generally disclosed for synthesis of porous particles from a solution formed from a leaving agent, a surfactant, and a soluble metal salt in a solvent. The surfactant congregates to form a nanoparticle core such that the metal salt forms about the nanoparticle core to form a plurality of nanoparticles. The solution is heated such that the leaving agent forms gas bubbles in the solution, and the plurality of nanoparticles congregate about the gas bubbles to form a porous particle. The porous particles are also generally disclosed and can include a particle shell formed about a core to define an average diameter from about 0.5 μm to about 50 μm. The particle shell can be formed from a plurality of nanoparticles having an average diameter of from about 1 nm to about 50 nm and defined by a metal salt formed about a surfactant core. |

1. A porous particle comprising a particle shell formed about a hollow core to define an average diameter from about 0.5 μm to about 50 μm, wherein particle shell comprises a plurality of nanoparticles having an average diameter of from about 1 nm to about 50 nm, wherein the nanoparticles are defined by a metal salt formed about a surfactant core, and wherein the surfactant core comprises a surfactant molecule having a hydrophobic tail and a hydrophilic head. |
