Summary: This study investigated the recovery of indium using silica SBA-15 and titanosilicate ETS-10 under different conditions. The results showed that ETS-10 achieved maximum indium removal at pH 3.0, while SBA-15 performed best within the pH range of 5.0-6.0. The indium adsorption on SBA-15 followed the Elovich model, while its sorption on ETS-10 fitted the pseudo-first-order model. Langmuir and Freundlich adsorption isotherms were used to explain the equilibrium of the sorption process. Rating: 8/10

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 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: Titanosilicate-1 (TS-1) has garnered extensive attention for its unique shape-selective catalytic oxidation performance and excellent hydrothermal stability. However, diffusion and acid site restrictions hinder its industrial application. This paper comprehensively discusses the optimization of synthesis conditions to improve the content of framework Ti species and inhibit the formation of non-framework Ti species. It also summarizes methods for regulating the distribution, electronic environment, and coordination states of Ti species, as well as compares and analyzes specific methods for eliminating non-framework Ti species.

Summary: This research project introduces the preparation of a new mesoporous silica compound (AGC-ZM-2022) using a fatty acid as a template. Palmitic acid, a commonly found saturated fatty acid in animals, plants, and microorganisms, was used as the template to design the mesoporous silica compound. AGC-ZM-2022 was synthesized through the sol-gel method, using tetraethylorthosilicate as the silica source and palmitic acid as the template instead of traditional templates. The physical properties and structure of AGC-ZM-2022 were characterized using various techniques such as FT-IR, SEM, XRD, TEM, and BET.

Summary: Hierarchical TS-1 zeolites with multiple porosity levels have attracted increasing interest in recent years due to their improved mass transfer efficiency and enhanced accessibility of Ti active sites. Strategies for constructing hierarchical TS-1 zeolites, such as mesoporogen, mesoporogen-free, and demetallization methods, have been developed to address steric and diffusional issues, leading to improved catalytic performances in oxidative desulfurization and epoxidation reactions. Effective characterization methods for Ti species and hierarchical zeolite structures have been described, along with current challenges and future development perspectives for preparing hierarchical TS-1 zeolite catalysts.

Summary: Naproxen was impregnated into mesoporous SiO2 SBA-15 using the Supercritical Solution Impregnation (SSI) technique. The percentage of naproxen impregnated decreased with increasing CO2 density and with the addition of ethanol, ethyl acetate or menthol. The impregnated naproxen on SiO2 became amorphous and showed interaction with SiO2 support. Release tests showed a sustained release system with a slower rate compared to pure naproxen due to the interaction and diffusion of the drug.

Summary: MOF materials with adjustable pore structure and polymetallic sites have been explored as electrocatalysts for OER. Bimetallic materials show higher electrocatalytic activity than monometallic materials, while carbon-coated and doped MOF catalysts exhibit stable and good OER activity. The synergistic interaction between polymetallic active sites effectively improves the intrinsic activity of MOF on OER.

It is found that the functionalized sulfonic acid group not only accelerates the conduction of lithium ions, but also repels polysulfide anions through electrostatic interactions. The performance of the batteries is significantly improved with the use of this functionalized separator.

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.

Summary: This study presents a new method for preparing a microporous Ni2P/C catalyst with high catalytic activity. The redox reaction and carbon matrix formation during high-temperature treatment contribute to the stability and activity of the catalyst. Experimental and analytical results suggest that the microporous structure of the composite plays a crucial role in its catalytic performance. These findings are important for practical applications of efficient hydrogen production by water electrolysis.

Summary: First principles calculations were used to investigate the pathway for methylation of benzene with methane catalyzed by MFI type zeolite-supported Co species. The strong adsorption of benzene on Co is found to lower the activation energy for methane dissociation and promote the formation of toluene precursor. The activation energy of methane dissociation is also affected by the Al-Al distance.
