The visible light‐driven transformation of chemical compounds in combination with the liberation of H 2 is highly attractive. Herein, we report on a photocatalyst that allows the acceptorless dehydrogenation of benzylamine. Upon light absorption, free charge carriers are generated and used for the concerted imine formation and liberation of H 2 . Our photocatalyst consists of CdS as a light harvesting semiconductor supported on colloidal metal‐organic framework crystallites. The decoration with co‐catalytic nickel nanoparticles promotes hydrogen evolution and, in addition, stabilizes the CdS component under irradiation.
