Bismuth oxide subacetate (CH₃COO(BiO); BiOAc) with a large band gap energy (E_g) was first applied as an ultraviolet-light-driven photocatalyst in our group. MoS₂ nanoflowers have been used to improve the visible-light photocatalytic activity of bismuth-based semiconductors with wide E_g because of their good visible-light response. Herein, the grinding-assisted solid-state reaction method was used to prepare a MoS₂/BiOAc composite to improve the visible-light photoreactivity of BiOAc. As compared with commonly used wet chemical and hydrothermal routes, the grinding-assisted synthesis facilitated heterogeneous nucleation, which was beneficial to achieving close contact and subsequent charge transfer and separation at the interfaces, resulting in enhanced photocatalytic activity for malachite green, methylene blue, and antibiotic tetracycline degradation under visible-light irradiation. Notably, the dispersion in the mixing solution of ethanol and water (v/v=1) of MoS₂ nanosheets induced self-assembly into flower-like nanostructures, thus enhancing the photocatalytic activity of MoS₂/BiOAc. A possible mechanism for visible-light photocatalysis of MoS₂/BiOAc was proposed.

具有较大带隙能（E _g）的低乙酸氧化铋（CH ₃ COO（BiO）; BiOAc）首先被用作紫外线驱动的光催化剂。MoS ₂纳米花由于其良好的可见光响应而被用于改善具有宽E _g的铋基半导体的可见光光催化活性。在此，使用研磨辅助固相反应法制备MoS ₂/ BiOAc复合材料可改善BiOAc的可见光光反应性。与常用的湿法化学和水热途径​​相比，研磨辅助合成促进了异相成核，这有利于实现紧密接触以及随后界面处的电荷转移和分离，从而增强了对孔雀石绿，亚甲基蓝和亚甲基蓝的光催化活性。抗生素四环素在可见光照射下降解。值得注意的是，MoS ₂纳米片在乙醇和水（v / v = 1）的混合溶液中的分散引起自组装成花状纳米结构，从而增强了MoS ₂ / BiOAc的光催化活性。提出了MoS ₂ / BiOAc可见光光催化的可能机制。
