Abstract

Nanostructured mixed titanosilicate materials have great potential for applications (e.g. (photo)catalysis) but are susceptible to phase segregation. Here, we follow the structural and energetic evolution of mixed (Ti_xSi_1−xO₂)_n nanosystems with increasing size. Unlike in the bulk, intimate homogeneous TiO₂–SiO₂ mixing is predicted to be energetically favourable in nanoclusters.
