A new quaternary crystalline catalyst was obtained by a mixed hydrothermal method of integrating inorganic semiconductors, titanium oxide cluster (TOC) and molecular redox centers orderly into metal organic framework (MOF) materials. It shows a hydrogen production rate 3711.53 μmol g−1 h−1 under visible light irradiation, exceeds most of the same type of catalyst reported in recent years, and a favorable stability with. The excellent performance of the CdS/TOC/UiO‐67‐bpy/Co composites due to efficient promotion of photo‐induced carrier separation and migration, and offering abundant active sites for generating hydrogen. This work will help to guide the preparation of new efficient and stable photocatalysts and promote the effective conversion of solar energy to chemical energy. Through a new design strategy, we obtain an effective quaternary photocatalyst that shows an efficient photocatalytic hydrogen production performance up to 3711.53 μmol g−1 h−1 and good cycle stability.
