Title: METHOD FOR PREPARING POROUS INORGANIC PARTICLES
Abstract:
The present specification relates to a method for preparing porous inorganic particles, the method comprising the steps of: (a) preparing an emulsion comprising an inorganic precursor and a polar solvent; (b) adding an organic solvent to the emulsion of step (a) to swell emulsion particles; (c) mixing the swollen emulsion of step (b) with polymer particles having a positive charge on the surface thereof; (d) adding a surfactant to the mixture of step (c) and removing the organic solvent; (e) adding an initiator to the result of step (d) to polymerize the same; and (f) firing the result of step (e) to remove the polymer particles so as to form macropores.
