Over-Reduced Core–Shell Au@CoOx-Co with Strong Interfacial Interactions for Photoassisted Peroxymonosulfate Activation

“…12,13 Additionally, plasmonic metal, gold (Au), as an example, could provide further photoresponsive properties and enhanced light harvesting for optical modulation. 14,15 Constructing core@shell architecture represents an appealing route to further optimize the properties of metal− metal oxide nanocomposites, which maintains the maximum surface area of the shell component for enhanced application potential. However, spatially separating the core and isolating the shell composition allows mechanistic elucidation of interactions between the metal core and metal oxide shell.…”

“…Commonly, metal oxide as supports are widely used to modulate metal nanoparticles in nanocomposites due to their ability to not only prevent aggregation , but also form intimate contact with metals for efficient charge transfer and provide structural or electronic effect tuning through selective oxides. − Remarkably, the modulation of metal oxide properties by the metal component also needs constant investigation. The metal component provides excellent carrier conductivity, exciton separation, and transfer capabilities to promote redox reaction. , The modulated electronic structure of the metal oxide can alter photoelectronic properties and enhance structural stability. , Additionally, plasmonic metal, gold (Au), as an example, could provide further photoresponsive properties and enhanced light harvesting for optical modulation. , Constructing core@shell architecture represents an appealing route to further optimize the properties of metal–metal oxide nanocomposites, which maintains the maximum surface area of the shell component for enhanced application potential.
