Summary: We propose a facile approach to prepare graphene oxide (GO) composites with lanthanide (Ln) oxide/hydroxide nanoparticles (Ln = La, Eu, Gd, Tb) under mild conditions. The mechanism of GO-Ln nanocomposite formation involves the coordination of Ln3+ ions to oxygen-containing groups of GO, followed by nanoparticle growth. The obtained nanocomposites show the honeycomb-like structure of graphene and the interaction between GO and Ln ions is confirmed. The size and distribution of Ln oxide/hydroxide nanoparticles on GO sheets vary for different lanthanides, with La-containing composites exhibiting the most homogeneous distribution. All GO-Ln nanocomposites are thermally less stable compared to pristine GO.

Summary: Nanocomposites containing gold nanoparticles (AuNPs) were prepared by stereolithography with the addition of a gold precursor. The resin and AuNPs were polymerized and formed independently, allowing optimization of the processes separately. Advanced electron microscopy revealed the distribution and morphology of the AuNPs, which were influenced by the precursor concentration and thermal treatments. The AuNPs' localized surface plasmon resonance modified the optical properties of the 3D-printed nanocomposites, enabling the design of advanced plasmonic platforms for surface-enhanced Raman spectroscopy (SERS).

Summary: An active copper catalyst with high-energy surfaces was prepared using the friction stir welding (FSW) technique, exhibiting excellent acidic hydrogen evolution reaction (HER) activity even surpassing that of Pt foil at high current densities (>66 mA cm(-2)). Density functional theory calculation revealed that the high-energy surface facilitated the adsorption of hydrogen intermediates, thereby accelerating the HER. The epitaxial growth induced by FSW opens a new pathway for engineering high-performance catalysts, and it also enables the mass production of low-cost catalysts, which is advantageous for industrial applications.

Summary: The valence state of Mo plays a critical role in the performance of catalysts for ammonia synthesis and nitrogen reduction reaction. However, the dissolution of Mo as MoO42- in alkaline electrolytes has hindered the study of the valence effect of Mo in nanoparticle catalysts. In this study, a MoO2+x catalyst enriched with surface Mo6+ was developed, which showed enhanced ammonia yield and Faradaic efficiency compared to the MoO2 catalyst without Mo6+. The stability and speciation of Mo6+ in the catalyst were also analyzed.

Summary: This study elucidated the effect of Ag's work function on the electrochemical reduction of CO2 to CO by controlling the ratio of exposed crystalline planes. It was found that a higher proportion of Ag(110) to Ag(100) leads to a lower work function, resulting in enhanced electrochemical activity and selectivity for CO production. This research demonstrates a promising strategy to improve the electrochemical performance of metal catalysts by tuning their work functions through regulating exposed crystalline planes.
