“…Typical yields ranged from 70 up to 86%. Furthermore, the complexes were thermally stable at the reaction conditions and no leaching of the complexes was observed [35] ( Figure 27). A different approach to prepare immobilized Schiff base complexes was presented by Rangappan et al [36] in 2016.…”

Mesoporous silica sieves are among the most studied nano-objects due to their stable pore structure and easy preparation. In particular, MCM-41 have attracted increasing research attention due to their chemical versatility. This review focuses on the synthesis and regioselective functionalization of MCM-41 to prepare catalytic systems. The topics covered are: mono and di-functionalized MCM-41 as basic and acid catalysts, catalysts based on metallic complexes and heteropolyacids supported onto MCM-41, metallic nanoparticles embed onto functionalized MCM-41 and magnetic MCM-41 for catalytic purposes.

Functionalized MCM-41 constitute a group of potent hybrid catalysts for organic reactions. Their pore size is large enough to house large substrate molecules, the large bulk of surface silanol groups helps in introduction of a variety of functionalities required for the catalytic action. The current review emphasizes the broad methodology for the synthesis of these catalysts, effect of functionalization on reaction parameters, stability, efficiency, selectivity, reusability along with limitations of these catalysts to organic transformations, from a green chemistry standpoint. Some selected mechanisms of catalytic action are also highlighted. The review demonstrates that surface functionalized MCM-41 constitute innovative and need based catalyst systems that catalyze reactions like Sonogashira, Suzuki, Heck, Friedel Craft reaction, Aldol and Knoevenagel condensation etc. Several other reactions like oxidation, reduction, dehydration, esterification, epoxidation, CÀ S, CÀ N, CÀ O and SÀ S coupling as well as multicomponent synthesis of bioactive heterocycles have also been reported. It is hoped that this review will improve the understanding of scientific community on how these versatile catalysts operate and will provide opportunities to further enhance their utility for chemical industry.

“…First, from the full spectrum scan, a new peak of Pb4f appears in the material, indicating that lead ions are adsorbed by the material (Figure 6a). Figure 6b shows the precise scanning spectrum of C1s, which can be divided into three peaks: C-C, C-N and C=O [39,40]. When lead ions are adsorbed, the binding energies of these three peaks all increase to different degrees, indicating that nitrogen and oxygen near carbon are involved in the adsorption process.…”

In this study, a hydrogel adsorbent was successfully synthesized using hydroxyapatite/acrylamide/βcyclodextrin to adsorb heavy metal ions and dyes in water. In the study, different contents of hydroxyapatite were added to the hydrogel, and then the mechanical properties and adsorption properties of the material were studied. The results show that the compressive strength of hydrogel added with hydroxyapatite increased by 37.1%. According to the adsorption isotherm model, the maximum adsorption capacity is 300mg/g. In addition, the preparation process of the composite hydrogel is simple, and can be used at a lower pH value, and can be used multiple times. Therefore, the material is of great signi cance to the treatment of pollutants.
