The rational design of heterojunction photocatalysts enabling fast transportation and efficient separation photoexcited charge carriers is the key element in visible light-driven photocatalyst systems. Herein, we develop a unique Z-scheme consisting NiMoO4 microflowers (NMOF) ZIF67, referred to as ZINM (composite), for purpose antibiotic degradation. ZIF67 was produced by solution process, whereas NMOF synthesized via coprecipitation with glycine surfactant. exhibited monoclinic phase highly oriented, interconnected sheet-like morphology. showed better optical transfer characteristics than its constituents, NiMoO4. Consequently, developed superior photocatalytic redox capability; ZINM30 (the composite 30 wt.% loaded) could degrade 91.67% tetracycline 86.23% norfloxacin within 120 min. This enhanced activity attributable reduced bandgap (Egap = 2.01 eV), morphology, high specific surface area (1099.89 m2/g), intimate contact between NiMoO4, which facilitated establishment heterojunction. Active species trapping tests verified that •O2− h+ were primary species, supporting proposed degradation mechanism. work highlights valid ZIF67/NiMoO4 system carrier and, therefore, antibiotics.
