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-C3N4/Pt@UiO-66, being composed of UiO-66 and Na-doped g-C3N4 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-C3N4/Pt@UiO-66 shows excellent photocatalytic H-2 production, far surpassing its corresponding single counterparts.
