The catalytic oxidation of benzene faces challenges in achieving high activity and selectivity. While single-atom catalysts present intriguing potential for this transformation, their practical implementation is hindered by intrinsic limitations the mass-specific activity. In context, few-atom cluster have emerged as an alternative, leveraging well-defined metal ensemble effects that enable precisely tailored active sites enhanced interatomic synergies. Herein, we introduce atomic supported on a graphitic carbonitride (CN) catalyst (Cu3/CN), exhibiting excellent performance selective to phenol, with superior turnover frequency (TOF) Cu1/CN (719 h-1 vs 280 h-1) suppressing phenol selectivity nanoparticle CuNP/CN (95.3% 77.2%). Multimodal mechanistic investigations unambiguously identify critical role adsorbed O* Cu site (Cu═O*) C-H-oxidation, verified both situ spectroscopic monitoring ex surface analysis. Complementary density functional theory calculations validate (Cu3) features higher d-band center larger charge transfer H2O2 molecule than isolated Cu1 site. sufficient stretches O-O bond facilitate formation Cu═O* species. Furthermore, resulting Cu3 demonstrates significant hybridization O 2p orbitals 3d at Fermi level, which endows it activation. appropriate effect unique architecture key its performances. This work establishes structure-performance correlation highlights optimizing functionality.
