In this contribution, we report a new type of Au nanoflowers-based nitroaromatic pesticides degradation platform which is fast, efficient, and simple. We found a straightforward, economically viable, and "green" approach for the synthesis and stabilization of relatively monodisperse Au nanoflowers of a diameter of about 100nm by using nontoxic chemical of hydroxylamine (NH2OH) without stabilizer and the adjustment of the pH environment. The hydroxylamine acted both as the reducing agent and capping agent for the synthesis and stabilization of Au nanoflowers in the system. The scanning electron microscope (SEM) and high-resolution transmission electron microscopy (HRTEM) techniques were employed to systematically characterize Au nanoflowers synthesized. Additionally, it was shown that these hydroxylamine stabilized Au nanoflowers functioned as effective catalyst for the reduction of pendimethalin in the presence of NaBH4 (otherwise unfeasible if NaBH4 is the only agent employed), which was reflected by the UV/Vis spectra of the catalytic reaction kinetics. Importantly, the novel degradation platform could be put in use in two different practical soil samples with satisfactory results. To demonstrate the feasibility and universality of our design, two other nitroaromatic pesticides, trifluralin and p-nitrophenol , were selected and were successfully degraded using this degradation platform.
