    摘要: 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.

    摘要: A membrane structure is provided. The membrane structure includes a polymer layer having a plurality of pores; and a ceramic layer disposed on the polymer layer. The ceramic layer has a plurality of substantially unconnected pores. Each of the substantially unconnected pores is in fluid communication with at least one of the pores of the polymer layer. A method of manufacturing a membrane structure is provided. The method includes the steps of providing a polymer layer having a plurality of pores; and disposing a ceramic layer on the polymer layer. Disposing a ceramic layer includes depositing a metal layer on the polymer layer; and anodizing the metal layer to convert the metal layer into a porous layer. At least one of the depositing step and the anodizing step is performed as a continuous process. Alternatively, at least one of the depositing and the anodizing step is performed as a batch process.

    摘要: A porous membrane for separation of carbon dioxide from a fluid stream at a temperature higher than about 200° C. with selectivity higher than Knudsen diffusion selectivity. The porous membrane comprises a porous support layer comprising alumina, silica, zirconia or stabilized zirconia; a porous separation layer comprising alumina, silica, zirconia or stabilized zirconia, and a functional layer comprising a ceramic oxide contactable with the fluid stream to preferentially transport carbon dioxide. In particular, the functional layer may be MgO, CaO, SrO, BaO, La2O3, CeO2, ATiO3, AZrO3, AAl2O4, A1FeO3, A1MnO3, A1CoO3, A1NiO3, A2HfO3, A3CeO3, Li2ZrO3, Li2SiO3, Li2TiO3 or a mixture thereof; wherein A is Mg, Ca, Sr or Ba; A1 is La, Ca, Sr or Ba; A2 is Ca, Sr or Ba; and A3 is Sr or Ba.
