“…[13±15] Although Ti-ZSM-48 was also prepared, it showed no catalytic activity due to pore size constraints. [16] Recently, [17] it has been proposed that the presence of titanium(iv) ions impedes or lowers the nucleation rates in the organothermal synthesis of a titanium-ferrierite system but it was possible to prepare a titanium-containing analogue by seeding with a silicon ferrierite. Unfortunately, the sample had no detectable catalytic activity.…”

“…Unfortunately, the sample had no detectable catalytic activity. [17] In our case, we succeeded in synthesizing directly, without adding seeds, the laminar Ti-PreFER, [11] following the same procedure used for Al-PreFER. The UV/Vis spectrum of the sample shows a single absorption band centered at l $ 210 nm corresponding to an isolated framework of tetrahedrally coordinated titanium atoms.…”

“…However, the concentration of framework Al atoms in the zeolite catalysts was different, which led to the different concentration of acid sites in the catalysts and thus influence the catalytic results. In 1998, Kotasthane et al prepared a new family of titanium silicate FER (Ti-FER) zeolite using solvothermal synthesis method in the presence of silica-FER seeds [111]. Very similarly, the first successful synthesis of vanadium silicates with FER structure (V-FER) was obtained using a similar solvothermal synthesis route.…”

As one of the most important porous materials, zeolites with intricate micropores have been widely employed as catalysts for decades due to their large pore volume, high surface area, and good thermal and hydrothermal stabilities. Among them, ferrierite (FER) zeolite with a two-dimensional micropore structure is an excellent heterogeneous catalyst for isomerization, carbonylation, cracking, and so on. In the past years, considering the important industrial application of FER zeolite, great efforts have been made to improve the synthesis of FER zeolite and thus decrease the synthesis cost and enhance catalytic performance. In this review, we briefly summarize the advances in the synthesis of FER zeolite including the development of synthesis routes, the use of organic templates, organotemplate-free synthesis, the strategies of morphology control, and the creation of intra-crystalline mesopores. Furthermore, the synthesis of hetero-atomic FER zeolites such as Fe-FER and Ti-FER has been discussed.

“…Meanwhile, the hydrothermal and thermal stability of the interlayer expanded structure are not as good as that of the conventional 3D structure. There are also reports about the preparing of titanosilicate of FER topology in non-aqueous alkali-free seeded system [27] or of CDO topology possessed ferrierite sheets [28]. But they only mentioned the synthesis of these materials, the catalytic properties are not involved.…”

Ti-PLS-3, a kind of layered titanosilicates of FER topology was developed by hydrothermal synthesis with the help of using pure silica PLS-3 as seed. The Si/Ti ratio of this material can be adjusted in a wide range from 20−∞. The structure and active sites of Ti-PLS-3 were detected by various characterization. After mild acid treatment to eliminate the hexa-coordinated extra-framework Ti species, the resulting material turned out to be a more effective catalyst for epoxidation of 1-hexene with H 2 O 2 than reported FER type Ti-containing material Ti-FER.
