Oxidation of nanoscale Au-In alloy particles as a possible route toward stable Au-based catalysts.
The oxidation of bimetallic alloy nanoparticles comprising a noble and a nonnoble metal is expected to cause the formation of a single-component surface oxide of the nonnoble metal, surrounding a core enriched with the noble metal. Studying the room temperature oxidation of Au-In nanoparticles, we show that this simple picture does not apply to an important class of bimetallic alloys, in which ...
متن کاملThermally Stable TiO2‐ and SiO2‐Shell‐Isolated Au Nanoparticles for In Situ Plasmon‐Enhanced Raman Spectroscopy of Hydrogenation Catalysts
Raman spectroscopy is known as a powerful technique for solid catalyst characterization as it provides vibrational fingerprints of (metal) oxides, reactants, and products. It can even become a strong surface-sensitive technique by implementing shell-isolated surface-enhanced Raman spectroscopy (SHINERS). Au@TiO2 and Au@SiO2 shell-isolated nanoparticles (SHINs) of various sizes were therefore pr...

متن کاملSelective oxidation of veratryl alcohol with composites of Au nanoparticles and graphene quantum dots as catalysts.
Veratryl alcohol can be oxidized to veratryl aldehyde or veratric acid with excellent selectivity and efficient conversion under acidic and alkaline conditions using Au nanoparticles and graphene quantum dot composites (Au/GQDs) as catalysts.
متن کاملSub-5 nm nanobowl gaps electrochemically templated by SiO2-coated Au nanoparticles as surface-enhanced Raman scattering hot spots.
Large-area submonolayer and monolayer Au nanoparticle (NP) arrays with sub-5 nm nanobowl gaps for giant electromagnetic enhancement were created by partially embedding SiO2-coated Au NP arrays in an electrochemically deposited Au film, followed by the removal of the SiO2 shells.
