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.

The emergence of bismuth molybdate (Bi2MoO6) as a promising visible-light catalyst has prompted researchers to increasingly focus on its investigation. To elucidate the impact different preparation methods morphology and photocatalytic properties Bi2MoO6, samples were synthesized via solvothermal, in situ conversion, solution combustion, precipitation, sol-gel techniques. physicochemical Bi2MoO6 characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), particle size analysis (PSA), fluorescence, photocurrent measurements. materials’ ability degrade Rhodamine B (RhB) was evaluated. results demonstrated that crystallinity, morphology, bandgap width, photogenerated carrier recombination varied significantly depending method. Among these methods, solvothermal route proved most effective, yielding with highest activity, achieving 97.5% RhB degradation within 25 min light exposure. low rate attributed large specific surface area narrow (2.71 eV). This study provides valuable insights into preparing enhanced properties.
