Herein, cobalt (Co)‐based metal–organic zeolitic imidazole frameworks (ZIF‐67) coupled with g‐C 3 N 4 nanosheets synthesized via a simple microwave irradiation method. SEM, TEM and HR‐TEM results showed that ZIF‐67 were uniformly dispersed on g‐C 3 N 4 surfaces and had a rhombic dodecahedron shape. The photocatalytic properties of g‐C 3 N 4 /ZIF‐67 nanocomposite were evaluated by photocatalytic dye degradation of crystal violet (CV), 4‐chlorophenol (4‐CP) and photocatalytic hydrogen (H 2 ) production. In presence of visible light illumination, the photocatalytic dye results showed that 95% CV degradation and 53% 4‐CP degradation within 80 min. The H 2 production of the g‐C 3 N 4 /ZIF‐67 composite was 2084 μmol g −1 , which is 3.84 folds greater than that of bare g‐C 3 N 4 (541 μmol g −1 ).
