"Brick and Mortar" Strategy for the Formation of Highly Crystalline Mesoporous Titania Films from Nanocrystalline Building Blocks

Original language description

We present a novel "brick and mortar" strategy for creating highly efficient transparent TiO2 coatings for photocatalytic and photovoltaic applications. Our approach is based on the fusion of preformed titania nanocrystalline "bricks" through surfactant-templated sol-gel titania "mortar", which acts as a structure-directing matrix and as a chemical glue. The similar chemical composition of both bricks and mortar leads to a striking synergy in the interaction of crystalline and amorphous components, suchthat crystallization is enhanced upon thermal treatment and highly porous and highly crystalline structures are formed at very mild conditions. Coatings with a broad variety of periodic mesostructures and thicknesses ranging from few nanometers to several micrometers are accessible using the same organic template, and the final structures are tunable by varying the fraction of the "bricks".
