• coordinated Ti [35][43]. Therefore, in the last decade, research has been focused on the combination of mesoporosity and zeolitic features [20][44][45][46][47][48][49][50]. Many promising materials, such as MTS-9 [51] and Ti-MMM-1 [52] have already been developed. The ultimate goal is to develop a “true

• that give rise to an enhanced catalytic performance in comparison with their purely zeolitic and/or mesoporous counterparts [51][52][57][58][59]. MTS-9 for example [51], gives rise to a higher catalytic activity in the epoxidation of styrene than Ti-MCM-41 and shows a selectivity and activity similar

• to TS-1 zeolite. In the hydroxylation of 2,3,6-trimethylphenol, MTS-9 is more active than both Ti-MCM-41 and TS-1. However, there are also examples of combined zeolitic/mesoporous materials, wherein there is no significant improvement when a comparison is drawn with standard zeolites or mesoporous
