Summary: The removal of zinc ions from water was studied using two types of ordered mesoporous silica (SBA-15 and SBA-16). Both materials were modified with APTES and EDTA through post grafting methods. The modified adsorbents were characterized by various analytical techniques, and the structural integrity was maintained. Optimal adsorption conditions and maximum adsorption capacity were determined through experimental tests, and the regenerated adsorbent showed no significant decline in adsorption efficiency.

Summary: The efficiency of Cu(II) removal from aqueous solution by silica SBA-15 and titanosilicate ETS-10 was investigated. The maximum adsorption capacity of both adsorbents was determined by studying various experimental parameters. The Langmuir model was found to be the best fit to describe the equilibrium adsorption, with ETS-10 having a higher adsorption capacity than SBA-15. Pseudo-first-order and pseudo-second-order kinetic models were the most applicable to describe the adsorption kinetics. Thermodynamic parameters indicated that the adsorption of Cu(II) onto the two adsorbents is spontaneous and endothermic.

Summary: The one-pot Prins-Friedel-Crafts reaction catalyzed by large-pore zeolites is an environmentally friendly route to valuable heterocyclic compounds. The catalytic behavior of a set of MWW zeolite catalysts with varying textural properties and chemical compositions was investigated and compared to that of a large pore beta zeolite. The MWW zeolites showed similar selectivities towards targeted products containing a 4-arylhetrahydropyran moiety, with high concentration and enhanced accessibility of acid sites being key factors for achieving high conversion and selectivity.

Summary: Zeolites are key materials in the chemical industry, with diverse applications ranging from water purification to oil refining. Recent research has focused on specialized applications such as fine chemical synthesis and small organic compound separation, driving the need for new zeolites with unique structural and chemical properties. Tailored organic structure-directing agents, particularly the introduction of germanium, have led to the discovery of numerous new extra-large pore zeolites for selective catalysis. Furthermore, the germanosilicate chemistry provides unparalleled opportunities for tailoring zeolite-derived materials through controlled post-synthetic transformations, resulting in the development of porous materials with customized characteristics and properties.

Summary: Zeolites are important materials for research and industry, but current synthesis methods are limited. Harsh hydrothermal conditions are required for classical procedures, and post-synthesis methods are only suitable for certain parent materials. However, by stopping degradation at intermediate structures, a new highly crystalline zeolite, IPC-20, was obtained from the parent zeolite IWV through seed-assisted crystallization and gentle transformation. This approach can be applied to any labile material with a staged structure.

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.

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.
