Isolated single‐atom platinum (Pt) embedded in the sub‐nanoporosity of 2D g‐C3N4 as a new form of co‐catalyst is reported. The highly stable single‐atom co‐catalyst maximizes the atom efficiency and alters the surface trap states of g‐C3N4, leading to significantly enhanced photocatalytic H2 evolution activity, 8.6 times higher than that of Pt nanoparticles and up to 50 times that for bare g‐C3N4.
