Claim:
1. A method of making a nanoporous structure comprising a matrix and at least one nanosized pore within the matrix, the method comprising: contacting at least a portion of a templated matrix with an acid solution, wherein the templated matrix comprises: a matrix comprising a sol-based ceramic selected from the group consisting of a sol-based silicate, a sol-based alum inate, a sol-based aluminosilicate, a sol-based titanate, a sol-based zirconate, and combinations thereof; and (ii) at least one nanosized template within the matrix, wherein each nanosized template comprises a core that comprises an inorganic oxide selected from the group consisting of SiO dissolving essentially all of the inorganic oxide of the core of the at least one nanosized template and form the at least one nanosized pore within the matrix thereby forming the nanoporous structure, wherein the functional coating defines at least a portion of the nanosized pore within the matrix.
