Over the past few years, nanotechnology and nanomaterials have played a crucial role in the agriculture sector. Notably, among different types of nanomaterials, metal–organic frameworks (MOFs) have attracted significant attention owing to their porosity, organic composition, biocompatibility, and tailored structural and compositional properties. In this research work, we have effectively prepared four types of MOFs including ZIF-8, ZIF-67, PFC 6, and PFC-7. Interestingly, among all the prepared MOFs, ZIF-67 exhibited exceptional performance. With the aim to further improve the efficacy of ZIF-67, we decorated it with SnO₂. Among the as-prepared samples, the optimal sample 5SnO₂/ZIF-67 nanocomposite exhibited exceptional efficiency in terms of its high chemical and thermal stability, large surface area, selective antipathogenic activities, high catalytic activities, and disease resistance properties. Based on our various characterization techniques, such as XRD, DRS, PL, FS, BET, FT-IR, and RAMAN, it has been confirmed that the incorporation of SnO₂ into ZIF-67 leads to adjustments in band gaps, enhanced stability, modulated photo-electrons, large surface area, abundant active sites, and upgraded adsorption and selectivity for antipathogenic and pesticide degradation activities. As compared to pure ZIF-67, the most active sample 5SnO₂@ZIF-67 showed ∼4.5 and ∼2.6 times significant improvement for glyphosate (GLY) and acephate (ACPH) degradation, respectively. Remarkably, our prepared samples also offered potent performances against various pathogens in Luria–Bertani medium. Based on the scavenger tests, ·OH and O₂⁻ are respectively responsible for GLY and ACPH decomposition. Accordingly, the activity improvement mechanism and biochemical pathways are proposed. Finally, our novel research work will provide a gateway for the fabrication of MOF-based green nanomaterials that will unlock a wide range of opportunities and applications in antipathogenic and pesticide degradation activities and tomato plant growth.

设计基于 MOF 的绿色纳米材料以增强番茄植株的病原体抗性和农药降解


在过去的几年里，纳米技术和纳米材料在农业领域发挥了至关重要的作用。值得注意的是，在不同类型的纳米材料中，金属有机框架 （MOF） 因其孔隙率、有机组成、生物相容性以及定制的结构和成分特性而引起了极大的关注。在这项研究工作中，我们有效地制备了 ZIF-8 、 ZIF-67 、 PFC 6 和 PFC-7 四种类型的 MOFs。有趣的是，在所有制备的 MOF 中，ZIF-67 表现出优异的性能。为了进一步提高 ZIF-67 的功效，我们用 SnO₂ 对其进行了修饰。在制备的样品中，最佳样品 5SnO₂/ZIF-67 纳米复合材料在高化学和热稳定性、大表面积、选择性抗病活性、高催化活性和抗病性能方面表现出卓越的效率。基于我们的各种表征技术，如 XRD、DRS、PL、FS、BET、FT-IR 和 RAMAN，已经证实 SnO₂ 掺入 ZIF-67 会导致带隙调整、增强稳定性、调制光电子、大表面积、丰富的活性位点，以及升级的吸附和选择性抗病原和农药降解活性。与纯 ZIF-67 相比，最活跃的样品 5SnO₂@ZIF-67 的草甘膦 （GLY） 和甲胺磷 （ACPH） 降解分别显示出 ∼4.5 和 ∼2.6 倍的显著改善。值得注意的是，我们制备的样品在 Luria-Bertani 培养基中也提供了针对各种病原体的强效性能。 基于清道夫测试， ·OH 和 O₂⁻ 分别负责 GLY 和 ACPH 分解。据此，提出了活性提高机制和生化途径。最后，我们的新颖研究工作将为制造基于 MOF 的绿色纳米材料提供一个门户，这将在抗病原和农药降解活性以及番茄植物生长方面开启广泛的机会和应用。
