Summary: The aim of this study was to investigate the electrogeneration of iron-based solids and their use in dye adsorption. Experiments were conducted to determine the efficiency of ferrous ion production at different pH levels and currents. The results showed that the current efficiency for Fe2+ was low and independent of the examined factors. Electrogenerated iron hydroxides were formed before possibly converting to dehydrated hydroxides such as magnetite. Adsorption experiments were carried out to study the adsorption of tartrazine on the electrogenerated iron oxyhydroxides. The adsorbent's crystallinity, surface area, pore volume, morphology, and elemental composition were also analyzed.

Summary: Xanthan gum-based hydrogels were synthesized as efficient adsorbents for dye pollutants removal from wastewaters. The adsorption mechanism was primarily attributed to electrostatic interactions and hydrogel swelling. The hydrogel exhibited a high theoretical q(max) towards Gentian Violet at pH 8 to 9 and could be regenerated with HCl for at least 4 cycles with over 99% dye removal efficiency.

Summary: In this work, mesoporous calcium-based adsorbents were prepared using an organogel called DMDBS as a soft template, which significantly increased the specific surface area of the adsorbent and enhanced its adsorption capability for fluoride removal. The physical properties and adsorption capacity of the adsorbents could be controlled by adjusting the calcination temperatures and DMDBS loadings. The synthesized mesoporous adsorbent showed promising potential for practical applications in fluoride-contaminated groundwater due to its stable fluoride adsorption capacity over a neutral pH range of 6-8.

Summary: Bacterial immunity to antibiotics is increasing due to inadequate drug use and antimicrobial resistance. This study explores the use of ordered mesoporous carbons modified with urea, thiourea, and cetyltrimethylammonium bromide as carrier platforms to enhance the activity of tebipenem pivoxil - a broad-spectrum beta-lactam antibiotic. The presence of functional groups on the carbon materials determines the amount of antibiotic released, especially at pH 7.0. The use of surfactant-functionalized carbon carriers improves the dispersion and diffusion of antibiotic molecules, resulting in better antimicrobial efficiency and solubility of tebipenem pivoxil.

Summary: Oxidizing mesoporous carbon CSBA-15 can effectively remove rhodamine B from aqueous solutions. The oxidation process reduces surface area and pore volume, but increases acidic oxygen functional groups, enhancing dye removal effectiveness. Optimal conditions for adsorption equilibrium were pH 12 and 60 degrees C, with equilibrium reached after approximately 1 hour. Kinetic studies showed a good fit to a pseudo-second-order model.

Summary: In this study, carbon xerogels were prepared through polycondensation in a water medium and improved their adsorption performance by oxidation and modification. The results indicate that the presence of amine groups on the surface of carbon xerogels enhances their adsorption capacity for dyes. The dye adsorption process is endothermic and spontaneous. In terms of adsorption kinetics, the pseudo-second-order model is more suitable for description.

Summary: This study investigates the importance of the interaction and position of the nitro group in the adsorption of 2-nitrophenol (2-NP), 4-nitrophenol (4-NP), and phenol by demineralized kraft lignin activated carbon (DKLAAC). The results show that the adsorption follows the order 2-NP > 4-NP > phenol, and both solubility and donor-acceptor complex mechanism play a significant role in the adsorption process. The experimental data fits well with the Langmuir adsorption isotherm and pseudo-second order kinetic models. The temperature study reveals that the adsorption process is endothermic and spontaneous with high affinity between DKLAAC and phenols.

Summary: This study investigates the effect of oxidative pretreatment of mesoporous carbon on the deposition of cobalt oxide phases. It was found that the oxidative pretreatment of mesoporous carbon influences the speciation of the deposited cobalt oxide phase. In addition, the activity of the electrocatalysts in the oxygen evolution reaction is positively correlated with the relative content of COO-type groups and negatively correlated with the relative content of COO-type groups on the carbon support. Moreover, a high relative content of COO-type groups on the carbon support is correlated with the presence of well-dispersed Co3O4 nanoparticles.

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.
