Abstract Solid‐state grinding is a simple and effective method to include guest species into the channels of ordered mesoporous materials with different degree filling. After calcination, monolayer or several monolayers can not only form highly dispersed oxide other surface on hosts whether template occluded in not, but also fill host thus lead nanowires nanoarrays. salt inclusion faster more convenient than routes. The absence solvent saves time otherwise needed for evaporation leads higher...

Direct generation of superbasicity on mesoporous silica SBA-15 was realized by tailoring the host-guest interaction, and calcium species were selected as guest in modifying SBA-15.
