Dynamic surface radical confinement in a compact CdS-CdIn₂S₄ semi-coherent heterojunction for highly efficient synergetic photocatalytic selective oxidation of toluene and enhanced hydrogen production.

ABSTRACT: Efficiently activating inert C-H bonds while maintaining control over the selective pathways of complex chemical reactions involving high-energy species remains a highly challenging and as-yet unattained objective. Herein, we propose a novel concept called 'dynamic local free radical confinement-mediated mechanism' to efficiently achieve synergetic selective oxidation of toluene and hydrogen generation for the first time via a CdS-CdIn₂S₄ semi-coherent heterojunction (CCS) under two-phase conditions. Surprisingly, the optimized CCS-2 exhibited amazing catalytic efficiency and long-term stability in gram-scale experiments and automatically separated the catalyst from the product. The mechanistic study indicates that the unstable semi-coherent interface in CCS-2
