Patent ID: 7955534

Claim:
A method for producing a mesoporous monolithic substrate of ceramic materials containing a metal constituent, comprising the following steps: a. providing a metal compound containing non metallic constituents and a metal constituent which is a precursor of the metal constituent of the ceramic materials; b. hydrolyzing the metal compound to be a sol; c. modifying the sol by mixing the sol with a matrix pore modifier to form a modified sol; d. preparing a model of the monolithic substrate of materials comprising a hollow housing having a first and second end, wherein the housing has a removable first and second stop for sealing the respective first and second end of the housing, and the inside of the housing contains a multiplicity of micro fibers which are aligned in a given direction within the housing; e. casting the modified sol into the model of the monolithic substrate of materials to form a cast modified sol, wherein the cast modified sol surrounds each of the microfibers; f. gelling the cast modified sol inside of the model to form a gel; g. aging the gel to be a syneresical gel; h. drying the syneresical gel to be a monolithic substrate of a dried and solidified gel which inside contains the multiple micro fibers; i. removing the monolithic substrate of the dried and solidified gel from the housing wherein the dried and solidified gel surrounds each of the multiple micro fibers; and j. forming a monolithic substrate of ceramic materials containing a multiplicity of open channels which are isolated from each other, have roughly the same size, and are all aligned in the same given direction, each of the multiplicity of open channels having a mesoporous inner surface, the open channels are formed by heating the monolithic substrate of materials containing the dried and solidified gel to eliminate the micro fibers positioned inside of the dried and solidified gel.
