As important industrial materials, microporous zeolites are necessarily synthesized in the presence of solvents such as in hydrothermal, solvothermal, and ionothermal routes. We demonstrate here a simple and generalized solvent-free route for synthesizing various types of zeolites by mixing, grinding, and heating solid raw materials. Compared with conventional hydrothermal route, the avoidance of solvents in the synthesis not only significantly reduces the waste production, but also greatly increases the yield of zeolite products. In addition, the use of starting solid raw materials remarkably enhances the synthesis efficiency and reduces the use of raw materials, energy, and costs.

Low-cost copper-amine complex was rationally designed to be a novel template for one-pot synthesis of Cu-SSZ-13 zeolites. Proper confirmation and appropriate size make this complex fit well with CHA cages as an efficient template. The products exhibit superior catalytic performance on NH(3)-SCR reaction.

Highly ordered mesoporous silica materials are hydrothermally synthesized at high temperature by using fluorocarbon–hydrocarbon surfactant mixtures as templates. Because of the high temperature of the synthesis, the obtained materials show complete silica condensation, which give rise to ultra‐stabile structures. JLU‐20 for example (see TEM image of calcined JLU‐20) has a fully condensed mesopore wall with a very high Q4/Q3 ratio of 6.5.

Mesoporous pure silica (MPS-9) is prepared using an assembly of preformed Silicalite-I nanoclusters with a triblock copolymer surfactant. The results of X-ray diffraction, transmission electron microscopy, and N 2 adsorption show that MPS-9 has a mesostructure that is similar to that of other mesoporous materials prepared from preformed zeolite nanoclusters, such as mesoporous aluminum silicates (MAS-7, MAS-9) and titanium silicate (MTS-9). However, MPS-9 shows weaker hydrothermal stability, in comparison to those other mesoporous materials prepared from preformed zeolite nanoclusters. On the other hand, three Al-SBA-15 samples synthesized from various routes are all much more hydrothermally stable than pure silica SBA-15. The previously proposed factors, including thicker pore walls, a disordered structure, the "salt effect", and zeolite-like connectivity, have been proven to be indeed favorable for the improvement of hydrothermal stability in this study. However, the introduction of heteroatoms (Al or Ti) in mesoporous materials is another favorable factor and can enhance the hydrothermal stability to a greater extent.

Lithiumzirconimidate (siehe Struktur) wurden nach der Deprotonierung von Zirconiummethylamid‐Komplexen oder der Addition von Methyllithium an Imidozirconium‐Komplexe isoliert. Quantitative Untersuchungen zur Säurestärke dieser konjugierten Basen von Zirconiumamidkomplexen ergaben, dass kinetische wie thermodynamische Größen des Protonenaustauschs von den weiteren Liganden am Zirconiumzentrum abhängen.
