摘要：

It is for the first time demonstrated that the plugged hexagonal-templated silicas can be facilely and controllably prepared from cheap sodium silicate without using any additives. The formation of constricted/plugged mesostructures is attributed to the non-uniform/ill-templating behaviours between silicate oligomers and P123 molecules under the synthesis conditions employed.
