Abstract:
1. A method for synthesis of a porous particle, the method comprising forming a solution from a leaving agent, a surfactant, a soluble metal salt, and a solvent, wherein the surfactant defines a surfactant molecule having a hydrophobic tail and a hydrophilic head; evaporating the solvent from the solution to cause a plurality of the surfactant molecules to congregate to form a nanoparticle core as the solvent evaporates from the solution, wherein the metal salt forms about the nanoparticle core to form a plurality of nanoparticles having an average diameter of from about 1 nm to about 50 nm; and heating the solution to cause the leaving agent to form gas bubbles in the solution, wherein the plurality of nanoparticles congregate about the gas bubbles to form a porous particle having an average diameter from about 0.5 μm to about 50 μm.
