Summary: Biodiesel obtained from the transesterification of vegetable oils contains polyunsaturated fatty esters which negatively affect its oxidation stability. Catalytic partial hydrogenation can upgrade biodiesel by converting polyunsaturated fatty esters into monounsaturated methyl oleate. In this study, polymer-supported palladium and nickel nanoparticles were tested as catalysts for upgrading biodiesels under mild conditions. The palladium catalyst showed high activity but poor selectivity, while the nickel catalyst exhibited lower activity but higher selectivity. The recyclability tests demonstrated that the nickel-based system can retain its activity and selectivity for at least five subsequent runs, providing an opportunity for waste biomass valorization.

Summary: This study reports the first example of strong metal-support interaction (SMSI) between palladium and gallium oxide within PdGa nanoparticles, demonstrating the important role of PdGa alloy and Ga2O3 coexistence in the formation of SMSI. The PdxGay NPs used as catalysts show higher catalytic performance for propyne semi-hydrogenation compared to conventional catalysts, indicating their potential in catalyst design and application. The reaction pathways of PSH on PdxGay NPs have been further elucidated by density functional theory calculations, providing a deeper understanding of SMSI and its implications for heterogeneous catalysis.

Summary: N-doping enhances the adsorption and charge of Pd, leading to higher catalytic activity, while also making it difficult for H to migrate on graphene due to the N doping. However, the N doping facilitates the overflow of H from Pd to graphene, reducing the energy barrier for migration. It is speculated that one migration path of H on N-doped graphene is through the Pd atom.

Summary: Metal-support interactions play a crucial role in optimizing the catalytic reactivity of oxide-supported Au nanoparticles, with reactive sites located not only at the interface but also on the metal surface. High-spatial-resolution IR nanospectroscopy measurements reveal that oxide support influences the reactivity pattern throughout the Au particles, leading to site-independent reactivity. In contrast, the reactivity of supported Pt particles is mainly activated on Pt sites rather than at the oxide-metal interface.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.

Summary: In this work, two metal organic frameworks (MOFs) containing {Cu2I2} clusters, Eu-CuI-INA and Sr-K-CuI-INA, were synthesized and characterized. Both materials have a three-dimensional structure with {Cu2I2} clusters coordinated by INA(-) ligands and Eu3+ or Sr2+ ions. The Sr-K-CuI-INA material exhibited sensitive fluorescence sensing behaviors towards cysteine and nitro-bearing molecules, showing potential applications in bio and explosive molecule sensing. This work provides a good reference for designing fluorescent MOF probes containing CuI molecules.

Summary: Na-ion batteries (NIBs) have attracted great interest as a potential technology for grid-scale energy storage due to the wide distribution, low cost, and environmental friendliness of sodium resources. However, their implementation is hindered by low rate capability and cycling stability caused by the large ionic size of Na+. In this study, a three-dimensional nanoarchitectured coral-like CoSe2@N-doped carbon (CL-CoSe2@NC) was synthesized, and it exhibited improved sodium storage properties with better electrode kinetics and a stable SEI film.
