The present invention provides an article having excellent performance in separation, catalytic reaction, filtration and the like, in which a liquid flow is limited to a flow passing through a porous substrate. An article includes a porous inorganic substrate housed in or bonded to a support made of an inorganic material, the porous substrate and the support comprising the porous substrate and the support Product and apparatus, and its formation, wherein the support is heated to a temperature effective to shrink the support onto the porous substrate such that a liquid tight contact is formed therebetween And methods of use are provided. In a preferred embodiment, the porous inorganic substrate is a porous monolith having a porosity of at least 5% and formed by a sol-gel method. [Selection] Figure 1 |
