摘要：

A one-pot synthesis procedure is described for the production of catalytically active titanium-incorporated mesoporous silica; the nature and accessibility of Ti(IV) sites derived from two different Ti sources was elucidated by means of catalytic tests, UV-VIS and photoluminescence spectroscopy.
