ABSTRACT:
A structure includes a substantially non-conductive frame having an exterior surface. The structure defines a plurality of passages that open to the exterior surface. Mesoporous material is disposed in the plurality of passages and is supported therein by the frame. In a method for making a mesoporous nanocrystalline titania hybrid material, a templating agent, an acid, and a titania precursor is mixed into a template liquid. A frame that defines a plurality of passages is placed into the template liquid. A solvent is evaporated from the template liquid, thereby forming a titania gel encapsulating the templating agent. The gel is heated to remove substantially the templating agent from the non-conductive frame and the titania, thereby leaving a mesoporous titania material.
