The present invention relates to a process for preparing mesoporous materials comprising the following steps in the sequence of a-b-c-d: (a) providing at least one dispersion of metal oxide nanoparticles (A) in a solvent (C) and at least one block copolymer (B) and optionally a solid substrate (S), (b) combining the at least one dispersion of metal oxide nanoparticles (A) with the at least one block copolymer (B), (c) removing the solvent (C) thus yielding a composite material (K), and (d) removing the at least one copolymer (B) from said composite material (K), wherein the block copolymer (B) comprises at least one alkylene oxide block (AO) and at least one isobutylene block (IB). The present invention further relates to mesoporous materials thus obtainable, and to their use as an electrode material, in electronic components, sensors, and dye-sensitized solar cells. The present invention finally relates to electronic components and dye-sensitized solar cells comprising the mesoporous materials. |
