The search for ideal model systems to investigate the role of different parameters in heterojunction composites for enhanced photocatalysis is a high‐priority target. Herein, a series of heterojunction composites, namely Na x ‐C 3 N 4 /Pt@UiO‐66, being composed of UiO‐66 and Na‐doped g‐C 3 N 4 with adjustable light absorbance and band structures, have been prepared with different Na contents, which exhibit a volcano curve towards photocatalytic H 2 production. Benefiting from the interplay of the two critical factors between light harvesting ability and electron transfer efficiency, the optimized Na 0.02 ‐C 3 N 4 /Pt@UiO‐66 shows excellent photocatalytic H 2 production, far surpassing its corresponding single counterparts.
