A Z-scheme photosensitive MOC/g-C3N4 composite catalyst for efficient visible-light driven half and overall water splitting

A photosensitive Pd 3 L 2 -type metal–organic cage (MOC-Q3) is successfully incorporated into IrO 2 /g-C 3 N 4 via non-covalent bonds to construct a Z-scheme single-atom IrO 2 /g-C 3 N 4 /MOC-Q3 photosystem for the overall splitting of water into H 2 and O 2 .
