Insights into interfacial mechanisms: CsPbBr 3 nanocrystals as sustainable photocatalysts for primary amine oxidation.

CsPbBr 3 nanocrystals (NCs) employed as a photocatalyst resulted in efficient benzylamine oxidation under oxygen atmosphere. Improved reaction yields stem from favorable -NH 2 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 CsPbBr 3 NC-catalyzed primary amine oxidation.
