Abstract
A reticulated ceramic product is provided having from about 5 to about 95 percent, preferably from about 10 to about 90, percent of the total porosity attributable to mesopores. Reticulated ceramic products provided include silicon oxide, aluminum oxide, zirconium oxide and ruthenium oxide. Reticulated ceramic products are prepared using a porous solid matrix as a template. The reticulated ceramic products are useful as chromatographic media, catalysts and adsorbents.
Claims16
A reticulated ceramic product comprising a porous ceramic particle having a total pore volume, wherein the total pore volume comprises
- (a) mesopore volume at a level of from about 5 to about 95 percent of the total pore volume, and
- (b) optionally, macropore volume at a level of from 0 to about 95 percent of the total pore volume, and
- (c) optionally, micropore volume at a level of from 0 to about 60 percent of the total pore volume
- wherein the sum of the mesopore volume, the micropore volume and the macropore volume is 100 percent of the total pore volume.
A method of making reticulated ceramic products comprising:
- disposing one or more liquid ceramic precursors throughout a portion of a porous solid matrix selected from the group consisting of porous SiO.sub.2, zeolites and porous polymer particles, forming a gel from the one or more liquid ceramic precursors disposed throughout said portion of the porous solid matrix, forming a ceramic from the gel, and removing a portion of said porous solid matrix.
