• 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

• accessible via the micropores. Here, it is clear that not all configurations with a combined micro- and mesoporosity inherently give rise to an enhanced molecular transport to or from the active sites in the micropores. However, this does not mean that these combined zeolitic/mesoporous materials without (or

• is desilication [48][50][65][66][67]. Extraction of Si atoms by base treatments (also denoted as pore-directing agents, PDAs) leads to a significant amount of intracrystalline mesoporosity while preserving the intrinsic acidity and structural integrity of the zeolite framework. Also during this
