Abstract Constructing heterostructured photocatalysts and depositing an appropriate co‐catalyst to facilitate charge separation are crucial steps improve photocatalytic H 2 evolution from water splitting. Herein, we reported the synthesis of C‐doped ZrO /g‐C 3 N 4 /Ni P (C‐ZrO P) composite based on UiO‐66‐NH material for production under visible‐light irradiation. The optimal rate over C‐ZrO /20 %Ni was 10.04 mmol g −1 h , which more than 10 times higher that (0.90 ). apparent quantum yield at 420 nm reached 35.5 %. A detailed analysis action mechanism revealed improved activity could be ascribed highly efficient spatial photoinduced carriers between g‐C as a result tightly bound structure its staggered band energy. presence Ni accelerates surface reaction well. This work demonstrates anchoring co‐catalysts onto metal–organic framework (MOF)/g‐C ‐derived metal oxide/g‐C hybrid is effective way obtain production.
