ABSTRACT OF THE DISCLOSURE HYDROPHOBIC INORGANIC STRUCTURES Three dimensional hydrophobic substantially inorganic porous structure comprises a myriad of cavities interconnected by holes in which the diameters of the cavities are in the range of from 0.5 to 100µm and the diameters of the holes are in the range of from 0.1 to 20µm the porosity of the structure having a narrow pore size distribution with the cavities having a pore volume of at least 2 cc/g for a predetermined 10µm range of sizes. The structure is preferably an inorganic oxide selected from the group comprising alumina, silica, titania, zirconia and mixtures thereof. The structure is preferably made from an oil-in-water emulsion with a silylating agent in the internal phase so as to render the structure hydrophobic.
