Summary: This study successfully synthesized MIL-53(Al) adsorbents through sonochemical-assisted synthesis and investigated their application in removing lead ions from aqueous solutions. The results showed that sonochemical-assisted synthesis could significantly reduce the synthesis time and increase the specific surface area of the adsorbents, thereby improving the mass transfer limitation in ion adsorption. The optimal conditions for lead ion removal were determined, and the applicability of adsorption equilibrium and kinetic models were verified. Furthermore, this study demonstrated the great potential of sonochemically synthesized MIL-53(Al) as an environmentally-friendly adsorbent for lead ion removal.

Summary: A green, novel, fast, and facile approach for synthesizing a SiO2/C nanocomposite series from rice husk (RH) through quenching and grinding techniques has been reported along with its application for the adsorptive removal of Reactive Red 120 (RR120) dye from an aqueous solution. The RH with a high surface area, large pore volumes, and two major components (SiO2 and C) showed promising adsorption capacity for RR120. The adsorption process was controlled by a physical mechanism and the thermodynamic parameters suggested that the adsorption was endothermic and spontaneous.

Summary: The simplest geminal diol CH2(OH)(2) is a crucial precursor for atmospheric formic acid formation. CH2(OH)(2) vapor can be generated by evaporating an aqueous formaldehyde solution prepared by dissolving paraformaldehyde under reflux.

Summary: In this study, a new lignocellulosic bioadsorbent derived from bilberry (Vaccinium myrtillus L.) leaves powder was utilized for the removal of methylene blue dye from aqueous solutions. The adsorbent was characterized by FTIR, SEM, and color analysis, and several factors including pH, contact time, adsorbent dose, initial dye concentration, temperature, and ionic strength were investigated. Equilibrium, kinetic, and thermodynamic studies were conducted to understand the mechanism of the adsorption process. The results showed that the bioadsorbent had a maximum adsorption capacity of 200.4 (mg g(-1)), which was higher than other similar bioadsorbents. The thermodynamic analysis indicated that the adsorption process was spontaneous, favorable, and endothermic, and physisorption played a role in the process. pH was found to have the greatest influence on the dye removal process, followed by contact time, temperature, adsorbent dose, ionic strength, and initial dye concentration. Overall, the bilberry-based bioadsorbent showed high efficiency in removing cationic dyes from aqueous solutions.

Summary: Hydrophobic coatings inspired by the lotus effect have gained popularity for their ability to solve various problems. The sol-gel method, utilizing silica, alumina, and titania, is explored as an environmentally friendly approach to produce water-based hydrophobic coatings. This study focuses on producing water-based hydrophobic coatings for cotton and polyester fabrics using a one-step sol-gel method. The coated fabrics exhibited improved hydrophobic properties, altered surface morphologies, and lower air permeability compared to uncoated fabrics. TEOS-PDMS coating provides a promising approach for enhancing the hydrophobic and surface properties of cotton and polyester fabrics.

Summary: Pt/C and SO42-/ZrO2 were used as catalysts for the synthesis of p-aminophenol through the catalytic transfer hydrogenation of nitrobenzene in water with formic acid as the hydrogen source. The optimal Pt loading for PAP selectivity was found to be 1 wt%. The presence of different valence states of Pt affected both the nitrobenzene hydrogenation and formic acid decomposition. Among different solid acid catalysts tested, SO42-/ZrO2 exhibited the highest catalytic activity for p-aminophenol formation. Under the optimized reaction conditions, the conversion of nitrobenzene reached 80.0%, with a selectivity of 47.6% for p-aminophenol.

Summary: The mechanism of the reaction between CO2 and styrene oxide for cyclic carbonate was revealed using density functional theory calculations. The noncatalytic reaction occurred via a concerted mechanism, while in the presence of guanidine and tetrabutylammonium iodide (TBAI) co-catalysts, the epoxide ring-opening by nucleophilic attack of an iodide anion was predicted to be the rate-determining step. Guanidine acted as the H-bond donor to activate styrene oxide, facilitating the reaction with a lower activation barrier.

Summary: Copper nanorods (Cu-NRs) exhibit significant plasmonic behavior and can act as efficient catalysts in redox processes and coupling. A benign decarboxylative approach, utilizing localized surface plasmon resonance (LSPR) assisted catalysis with Cu-NRs, has been developed for the production of alkane analogues from alkyl carboxylic acids under visible light. The catalyst shows a broad substrate scope and high functional group tolerance, without the need for an external oxidant or proton source. A plausible mechanism for this recyclable nano-catalyst has also been proposed based on control experiments.
