Abstract
This research investigates the effect of colloidal particles on the pr eparation of ordered mesoporous materials (M41S). It demonstrates that colloidal silica and colloidal titania particles promote the formatio n of these materials. Under similar conditions no ordered structure is observed without the colloidal particles. A heterogeneous nucleation mechanism is proposed based on these observations and is supported by direct evidence from transmission electron microscopy (TEM).
