We introduce the visible‐light photocatalytic H 2 evolution reaction as catalyzed by a cobaloxime/carbon nitride (C 3 N 4 ) noble‐metal‐free hybrid photosystem by using a continuous‐flow sampling reaction system. The photocatalytic H 2 evolution rate is highly dependent on the structure of C 3 N 4 , in which porous C 3 N 4 shows the best activity compared with bulk C 3 N 4 (lamellar) and C 3 N 4 nanosheets. When using porous C 3 N 4 , the system is neither affected by the solution pH, nor the C 3 N 4 concentration, nor the structure of the cobaloxime complex.
