Abstract Photocatalysis technology driven by solar energy is considered to be promising for solving crisis and environmental problems. Graphitic carbon nitride has been widely researched in the photocatalysis field due its suitable band positions, non‐toxicity, easy synthesis, high stability, low cost. However, slow separation rapid recombination of photogenerated carriers, poor visible light response specific surface area seriously limit photocatalytic activity g‐C 3 N 4 . Here, firstly, nanosheets with a large 152.2 m 2 g −1 which provide more surface‐active sites were prepared secondary calcination method. Next, MoS metal–organic framework (MIL‐101(Cr)) tightly bonded on form ternary /MoS /MIL‐101(Cr) heterojunction photocatalyst. In which, dual Z‐scheme photocatalyst composed , MIL‐101(Cr) was constructed facilitate migration charges. At same time, enhanced The optimal displayed highest methyl orange degradation (degradation efficiency 98% 60 min) under irradiation. Finally, mechanism electron transfer channel h + ‐·O − double oxidation proposed discussed.
