Asymmetric Cu Valence Engineering in CuInS2 Enables Selective Photocatalytic CO2-to-C2H4 Conversion

Achieving efficient C–C coupling in photocatalytic CO2 reduction is fundamentally limited by the inability of semiconductor surfaces to simultaneously stabilize and differentiate key intermediates (*CO and *CHO). In this work, we establish an asymmetric Cu valence engineering strategy in tetragonal CuInS2 that enable...
