Isolated single‐atom platinum (Pt) embedded in the sub‐nanoporosity of 2D g‐C 3 N 4 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‐C 3 N 4 , leading to significantly enhanced photocatalytic H 2 evolution activity, 8.6 times higher than that of Pt nanoparticles and up to 50 times that for bare g‐C 3 N 4 .
