Special Issue Information

Dear Colleagues,

The unique properties of mesoporous and zeolite-based nanomaterials predetermine their wide range of applications, from catalytic and adsorption processes to the development of new drug delivery systems. Modified mesoporous silicas, nanosized metal oxides, and hierarchical zeolites are successfully applied in processes for environmental protection, such as VOC oxidation and water purification, biomass valorization, and CO2 capture and utilization. The development of new nanostructured materials requires the application of a complex of routine and advanced physicochemical methods for their design.

This Special Issue aims to provide a forum for recent achievements in the synthesis and application of new nanomaterials. Experimental and theoretical studies on structural elucidation, adsorption, and catalytic processes in the presence of nanomaterials will be published.

We hope this Special Issue will demonstrate the capabilities and new applications of nanomaterials.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following: the synthesis, modification, and computational modeling of mesoporous silicas, nanosized metal oxides, zeolites, and their application.

We look forward to receiving your contributions.

Abstract
We successfully synthesize monodisperse sulfhydryl-modified mesoporous organosilica nanospheres (MONs-SH) via one-step hydrolytic condensation, where cetyltrimethylammonium chloride and dodecyl sulfobetaine are employed as dual-template agents with (3-mercaptopropyl)triethoxysilane and 1,2-bis(triethoxysilyl)ethane as the precursors and concentrated ammonia as the alkaline catalyst. The prepared MONs-SHs deliver a [...] Read more.
We successfully synthesize monodisperse sulfhydryl-modified mesoporous organosilica nanospheres (MONs-SH) via one-step hydrolytic condensation, where cetyltrimethylammonium chloride and dodecyl sulfobetaine are employed as dual-template agents with (3-mercaptopropyl)triethoxysilane and 1,2-bis(triethoxysilyl)ethane as the precursors and concentrated ammonia as the alkaline catalyst. The prepared MONs-SHs deliver a large specific surface area (729.15 m2 g−1), excellent monodispersity, and homogeneous particle size. The introduction of ethanol into the reaction systems could expand the particle size of the synthesized MONs-SH materials from 18 to 182 nm. Moreover, the successful modification of -SH groups endowed MONs-SHs with an excellent adsorption capacity (297.12 mg g−1) for Pb2+ ions in aqueous solution through ion exchange and complexation function. In addition, the established isotherm model and kinetic analyses reveal that the adsorption of Pb2+ ions on MONs-SHs follows the secondary reaction kinetic models, where both physisorption and chemisorption contribute to the adsorption of Pb2+ ions. The favorable recyclability of MONs-SHs is demonstrated with the maintained adsorption efficiency of 85.35% after six cycles. The results suggest that the synthesized MONs-SHs exhibit considerable application prospects for effectively eliminating Pb2+ ions from aqueous solutions. Full article

This paper proposes a method for synthesizing granular ZSM-23 zeolite with a high degree of crystallinity and hierarchical porous structure. This method is based on crystallizing granules composed of powdered ZSM-23 zeolite and a specially prepared amorphous aluminosilicate. It has been shown that these granules have superior mechanical strength compared to granular zeolite-containing materials, which are made from a mixture of ZSM-23 zeolite crystals and Al2O3. It has been demonstrated that when 0.5% of Pt granular ZSM-23 zeolite is used, with a high degree of crystallinity and a hierarchical porous structure, it exhibits higher activity and selectivity in the hydroisomerization of n-hexadecane compared to a bifunctional catalyst, which is a mechanical mixture of ZSM-23 zeolite crystals and Al2O3, with the metal deposited on the granules.
