The title compound, [Eu(III)(NO(3))(2)(C(24)H(28)Cl(2)N(6)O(2))]NO(3)·0.5CH(3)OH, is isostructural with the Gd(III) and Ho(III) complexes of the analogous macrocyclic ligand, with both Cl atoms replaced by methyl groups. The Eu atom exhibits a nine-coordinate distorted tricapped trigonal-prismatic coordination geometry. The methanol solvent mol-ecule is disordered about a twofold rotation axis with occupancies of 0.543 (12):0.457 (12).

Strong metal-support interactions (SMSIs) are essential for optimizing the performance of supported metal catalysts by tuning the metal-oxide interface structures. This study explores the hydrogenation of CO to methanol over Cu-supported catalysts, focusing on the synergistic effects of strong metal-support interaction (SMSI) and oxygen vacancies introduced by the CO treatment to the catalysts on the catalytic performance. Cu nanoparticles were immobilized on Mg-Al layered double oxide (LDO) supports and modified with nitrate ions to promote oxygen vacancy generation.

Green synthesis of nanoparticles (NPs) is preferred for its affordability and environmentally friendly approach. This study explored the synthesis and characterization of silver NPs (AgNPs) and examined their impact on the growth of Zea mays, both alone and in combination with nickel chloride (NiCl). A methanolic leaf extract was combined with silver nitrate to synthesize AgNPs.

Diffusion limitations and monofunctional acidity of ZSM-5 molecular sieves affect the catalyst stability and aromatic yield in the reaction of methanol to aromatics (MTA). In this study, based on ZSM-5 nanosheets as parent molecular sieves, Zn-modified hollow ZSM-5 nanosheets were obtained after hydrothermal treatment by adding ZIF-8 or zinc nitrate as a source of Zn while treating with different types and concentrations of alkali solutions. The physical and chemical properties of the fabricated samples and their catalytic performance of methanol aromatization were systematically investigated by a combination of XRD, TEM, N adsorption-desorption, NH-TPD, Py-IR, Al MAS NMR, Si MAS NMR, XPS, and TG characterization analyses and MTA experimental evaluation.
