Insights into interfacial mechanisms: CsPbBr₃ nanocrystals as sustainable photocatalysts for primary amine oxidation

CsPbBr₃ nanocrystals (NCs) employed as a photocatalyst resulted in efficient benzylamine oxidation under oxygen atmosphere. Improved reaction yields stem from favorable –NH₂ functional group interactions on the NC surface, while additional interactions with –OMe or –SMe functional groups post-product formation result in lower yields. These insights into interfacial interactions and mechanistic aspects advance sustainable chemical transformations through cost-effective and recyclable CsPbBr₃ NC-catalyzed primary amine oxidation.
