Summary: The review highlights the use of heterogenic catalysts based on porphyrins and phthalocyanines loaded on mesoporous materials for oxidation reactions, with a focus on alkane, alkene, and arene substrates. Mesoporous silica is a promising candidate for anchoring macrocycles and obtaining new catalysts. The catalytic reactions studied are primarily aimed at producing epoxides, alcohols, ketones, aldehydes, or acids, with a particular interest in the oxidation of cyclohexane and cyclohexene. Some reactions exhibit biomimetic processes resembling those catalyzed by the cytochrome P450 enzyme family.

Summary: CSPEs are potential materials to replace hazardous organic liquid electrolytes in LIBs, as they are easy to process and allow better interfacial contact. However, their poor mechanical strength, low ionic conductivity, and limited cycling stability hinder their practical applications. By utilizing PPC as the host matrix and highly mesoporous silica nanoparticles (MSNs) as the filler, a cost-effective, flexible, and stable CSPE was developed with enhanced physico-electrochemical properties. The interaction of Li+ with PPC and MSNs contributes to the excellent performance of the CSPE, opening up new possibilities for solid-state battery fabrication and engineering.

Summary: The impact of surface functionalization on mesoporous silica nanoparticle (MSN) carriers and the release of Fenofibrate (FNB) was investigated. The MSNs were modified with either (3-aminopropyl) triethoxysilane (APTES) or trimethoxy(phenyl)silane (TMPS), and the density of the functional groups was measured. The FNB loaded in the MSNs with ordered cylindrical pores showed amorphization, and the glass transition temperature slightly changed depending on the surface modification. Dielectric studies revealed multiple relaxations associated with different FNB populations and correlated their mobility with drug release profiles.

Summary: Polyoxometalate (POM) mesoporous silica-based materials with hydrophilic and hydrophobic properties have been designed as powerful heterogeneous catalysts in oxidative desulfurization (ODS) by adsorbing both H2O2 and sulphur-containing compounds simultaneously. The formation of charge transfer salts and the masking of silanol groups on the silica surface influence the catalysts' interactions and enhance the adsorption properties of non-polar dibenzothiophene (DBT). An extensive characterization of the materials has been performed using spectroscopy and electrochemical techniques to understand POM-surface and POM-POM anion interactions.

Summary: This study investigates the evolution and autoreduction behavior of Cu species in CuCl/NaY adsorbent during vacuum thermal activation. It is found that Cu species migrate from supercages to the nearby plane of the six-membered ring connecting the supercage and sod cage during vacuum activation. At 150 degrees C, vacuum autoreduction occurs, resulting in the formation of Cu+Cl- species. The results provide reference for the preparation of pi-complex adsorbents.

Summary: Hierarchical porous system with two types of mesopores provides a solution to the diffusion limitation in conventional zeolites. Cobalt oxide impregnated hierarchical ZSM-5 zeolite samples with intra- and inter-crystalline mesopores were synthesized using two different strategies. The physicochemical properties of the modified catalysts were analyzed, revealing distinct features given by the two mesoporous configurations. Catalytic activity analysis showed that Co-oxide/ZSM-5 with inter-crystalline mesopores exhibited higher activity in methane partial oxidation reaction compared to Co-oxide/ZSM-5 with intra-crystalline mesopores.
