In the present work, a novel (3D/2D/2D) prism-like ZGO‒MOF hybrid nanocomposite was successfully prepared via two-pot hydro-thermal process and employed as a catalyst for the degradation of organic persistent pesticide such as profenofos (PF). Due to more toxicity, the removal of such organic compounds are necessary in environmental aspects. The prepared nanocomposites were characterized and well explained using FT‒IR, XRD, UV‒DRS, SEM‒EDX, TEM, TGA‒DTA, PL and BET surface area measurements. The OH and O₂⁻ radicals was benign effective oxidative species involved in the ZGO‒MOF system for the mineralization of organic pollutants. Besides, ZGO‒MOF showed excellent photo-stability over five repetitive runs for the removal of organic pesticides with minimal drop on catalytic activity. Eventually, the intended photocatalytic mechanisms and degradation pathways of PF are readily determined in detail based on experimental results. The catalyst achieves excellent efficiency of about 94 %. Possible PQ oxidative pathways and their reaction intermediates were observed by LC–MS. Therefore, the pollutant which primarily oxidize into ring-ruptured components into innocuous products like H₂O, CO₂ and a few in-organic salts. With the concern of its environmental friendly, low‒cost, and benign simple synthesis, ZGO‒MOF was expected to be a promising choice for applications in wastewater management.

本文通过两锅水热法成功制备了新型（3D / 2D / 2D）棱柱状ZGO‒MOF杂化纳米复合材料，并用作催化降解有机持久性农药（如丙溴磷）的催化剂。 ）。由于毒性更大，因此在环境方面必须除去此类有机化合物。使用FT nanoIR，XRD，UV‒DRS，SEM‒EDX，TEM，TGA‒DTA，PL和BET表面积测量对制备的纳米复合材料进行了表征并得到了很好的解释。的OH和ö ₂ ^-自由基是ZGO‒MOF系统中涉及有机污染物矿化的良性有效氧化物质。此外，ZGO‒MOF在去除有机农药的五次重复运行中均表现出优异的光稳定性，且催化活性下降最小。最终，基于实验结果可以很容易地确定预期的PF的光催化机理和降解途径。该催化剂达到约94％的优异效率。LC-MS观察到可能的PQ氧化途径及其反应中间体。因此，主要氧化成环断裂成分的污染物变成H ₂ O，CO ₂等无害产物和一些无机盐。考虑到其环保，低成本和良性简单的合成，ZGO‒MOF有望成为废水管理中应用的有前途的选择。
