Co II cryptates bearing several substituents can photoreduce catalytically CO 2 to CO and, under longer irradiation times, to CH 4 , under visible light at room temperature in the presence of water. The cryptate with Br substituents showed the maximum activity, followed by the one with NO 2 . This work emphasizes how small differences are crucial to fine‐tune catalysts selectivity.
