  "abstract": "The immobilization of ruthenium based photocatalysts onto functionalized detonation nanodiamond (DND) particles is reported, providing recyclable heterogeneous systems for visible-light photoredox catalysis. The resulting nanoparticle-supported colloidal catalysts were evaluated in the αfunctionalization of carbamates and in three-component trifluoromethylation reactions of alkenes under visible light irradiation. In all cases, the heterogeneous systems display catalytic performances comparable to, or exceeding, those of their homogeneous counterparts. This enhanced activity is attributed to the electronic interaction between the Ru complex and the DND surface, which may facilitate interfacial charge transfer through favorable alignment of frontier orbitals. Additionally, the supported photocatalysts can be readily recovered and reused for more than 10 cycles without any significant loss of activity, demonstrating their robustness and stability. These results highlight the potential of nanodiamond-supported photocatalysts as efficient and sustainable alternatives for photoredox transformations involving noble metals.",
