Summary: A quick and convenient method was used to synthesize xyloside-based ligands using D-xylose as the starting material. The complexation properties of these ligands with Au(III) cations were studied using various techniques, including multinuclear NMR, mass spectrometry, and elemental analysis. Protometric titrations were conducted in aqueous solution at different pH conditions to investigate the binding of Au(III) cations to these ligands. Molecular calculations were also performed to obtain additional structural information. The catalytic activity of the most stable Au(III) complexes was evaluated for the homogeneous reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) in the presence of NaBH4.

Summary: In this work, a series of imidazolium- and triazine-based ionic polymers were synthesized by solvothermal and ball-milling methods for the catalytic cycloaddition reaction of CO2 and epoxides. The synthesized IPs showed satisfactory catalytic activity up to 99% yield, with easy reusability and no significant decrease in catalytic activity. The ball-milling synthesis of ionic polymers for CO2 conversion is expected to replace traditional solvothermal synthesis due to its straightforward and green synthesis route.

Summary: Many industrial processes produce waste with toxic and precious metal pollutants. Current remediation strategies lack the selectivity needed to effectively eliminate heavy metals. Sulfur is well known for its ability to selectively bind heavy metals. This study combines sulfur with charged monomers to form water-soluble polysulfides, which have demonstrated selective binding to metals and enhanced solubility in organic solvents.

Summary: Hydrogen spillover is the migration of H atom equivalents from metal nanoparticles to a support. This study measures weak, reversible H-2 adsorption on Au/TiO2 catalysts and determines the surface concentration of spilled-over hydrogen. The adsorption behavior of H* on the titania surface is found to increase with temperature, which is attributed to high proton mobility, configurational surface entropy, and increasing hydroxyl acid-base equilibrium constants.
