Sub-100 nm TiO2 mesocrystalline assemblies with mesopores: preparation, characterization, enzyme immobilization and photocatalytic properties.

The in situ formation of sub-100 nm solid frameworks stabilized against dissolution by the addition of nanoseeds allows the facile and controllable synthesis of TiO(2) (anatase) mesocrystalline structures with spherical shape, mesoporosity and sizes between 50 and 70 nm. As an example of their multifunctionality, these structures show good capabilities for enzyme immobilization and adequate photocatalytic properties.
