“…This approach has been used for the preparation of hybrid composite nanostructures based on zeolites [49][50][51] and MOFs [52], with applications in gas separation, CO 2 capture, and catalysis, among others. On the other hand, the opposite "bottle around ship" or "templated synthesis" approach consists of the assembly of the host material around the active or guest species [53,54].…”

Chemical routes for the synthesis of nanostructures are fundamental in nanoscience. Among the different strategies for the production of nanostructures, this article reviews the fundamentals of the bottom-up approaches, focusing on wet chemistry synthesis. It offers a general view on the synthesis of different inorganic and hybrid organic–inorganic nanostructures such as ceramics, metal, and semiconductor nanoparticles, mesoporous structures, and metal–organic frameworks. This review article is especially written for a wide audience demanding a text focused on the basic concepts and ideas of the synthesis of inorganic and hybrid nanostructures. It is styled for both early researchers who are starting to work on this topic and also non-specialist readers with a basic background on chemistry. Updated references and texts that provide a deeper discussion and describing the different synthesis strategies in detail are given, as well as a section on the current perspectives and possible future evolution.

“…Therefore, in the additive roasting process, the silicon in the additive (primarily composed of silicon and carbon) can partly replace magnesium and aluminum or be included in the nanocages of the original material framework, resulting in the negative framework charge forming the significant Brønsted acid site that can strongly activate the microregion and lead to partial rearrangement. 19 The rearrangement causes the microregion to be highly ordered on the microscopic scale, which results in forming abundant likemicrocrystals where the grain boundary phenomenon occurs, accounting for particular polycrystalline electron diffraction patterns. 20 Nevertheless, if illuminated by high-energy electron beams, the diffraction patterns will disappear with the reexcitation, as this crystal formation is not stable enough.…”

This paper reports the study of a novel mesoporous material modified from natural clinoptilolite (NC) through pore broadening and organic modification. In order to reveal purification capacity enhancement, micrographs obtained by performing high-resolution transmission electron microscopy on the materials were used to compare the inner structures of NC and mesoporous clinoptilolite (MC) at various magnifications. In MC, broader pores (from microporous to mesoporous) at the surface of MC and sublimation clouds of particles inside the pores and channels were found, while NC exhibited none of these features. The results obtained from energy-dispersive X-ray spectroscopy analysis indicate that the contents of impurities in MC were lesser than that of NC; the crystallinity of MC was also found to be more than that of NC. The decolorization rate of the MC material can reach up to 98·6%, while that of NC is 87%, and the removal rates of MC's chemical oxygen demand as analyzed by the dichromate method (COD Cr ) can reach 91·3%, while the rate for NC is 56%. The results indicate that the MC material has better adsorption with some mesoporous level (2-50 nm) on soluble organics, which is related to the pore diameter and the framework of the MC material from wastewater.

“…Very recently, Sun reported a "build-bottle-around-ship" synthesis of HPMo12 encapsulated in Y zeolite [34]. The preparation involves also the introduction of the polyoxometalate in a basic solution (pH = 10) of initiator containing silicon and aluminium (formed by dissolution of a natural clay in highly alkaline medium and hydrothermal synthesis) followed by a hydrothermal treatment at 130 °C for 48 h. The resulting solid was collected by filtration, treated with 0.01 M nitric acid at 60 °C for 10 h in order to remove the unencapsulated polyoxometalate and was finally washed with hot water.…”

An overview of the synthesis, characterization and catalytic applications of polyoxometalates/zeolites composites is given. The solids obtained by direct synthesis of the polyoxometalate in the presence of the zeolite are first described with their applications in catalysis. Those obtained by a direct mixing of the two components are then reviewed. In all cases, special care is taken in the localization of the polyoxometalate, inside the zeolite crystal, in mesopores or at the external surface of the crystals, as deduced from the characterization methods.
