Core–shell-structured Z-scheme CdS@MIL-88(A)Fe heterojunctions for efficient visible light photocatalytic oxidative coupling of benzylamines to imines

) were the primary active species responsible for the reaction. This work highlights the potential of the Z-scheme heterostructure design based on metal-organic frameworks (MOFs) for green photocatalytic organic transformations and provides valuable insights into the development of advanced photocatalysts for sustainable chemical synthesis.
