Abstract:
1. A process for making particles, comprising: (A) forming an emulsion comprising a hydrophobic phase dispersed in a hydrophilic phase, wherein the hydrophobic phase comprises a dopant; (B) adding a precursor material to the emulsion wherein the precursor material migrates to the hydrophobic phase; (C) adding to the emulsion a catalyst composing an aminofunctional silane, wherein (i) the catalyst penetrates into the hydrophobic phase and (ii) the precursor material reacts in the presence of the catalyst to form particles comprising the dopant therein, wherein (i) each of the particles is a porous solid and (ii) the dopant is distributed substantially homogenously within and is releasable by diffusion from each particle.
