Abstract
Superficially porous hybrid particles include hybrid solid cores that each contain an inorganic material and an organic material; and porous hybrid outer shells each include the inorganic and organic materials and having ordered pores, wherein the ordered pores have a median pore size ranges from about 15 to about 1000 Å with a pore size distribution (one standard deviation) of no more than 50% of the median pore size and produce at least one X-ray diffraction peak between 0.01° and 10° of a 2θ scan range; wherein the particles have a median size range from about 0.5 μm to about 100 μm with a particle size distribution (one standard deviation) of no more than 15% of the median particle size, wherein the inorganic material comprises a metal oxide selected from silica, alumina, titania or zirconia.
