Preventing and controlling agricultural non-point-source pollution, advancing the agricultural industry, and facilitating cation-π interaction to address cation instability and fertilizer loss are crucial for advancing agricultural sustainability. Due to the unique π-bond characteristics of GO (graphene oxide), it was selected as a cation carrier to improve fertilizer anti-loss capabilities and facilitate the effective release of nutrient ions. By adjusting the interface properties of GO, RGO (rippled graphene oxide) and CGO (crumpled graphene oxide) were successfully prepared, and their interactions with cations and the impact on sustained-release performance were studied. The selected optimal kinetic model provides a theoretical basis for material design. The results indicate that RGO-Zn1 (Zn/RGO = 16.7%) can not only effectively control agricultural non-point source pollution but also promote the cultivation of high-zinc rice. This study not only proposes an innovative solution for soil improvement and agricultural transformation and upgrading but also offers fundamental scientific insights into the cation-π interaction mechanism during transmembrane permeation.
防治农业面源污染、推进农业产业发展以及促进阳离子-π相互作用以解决阳离子不稳定性和肥料流失问题，对于推进农业可持续发展至关重要。由于氧化石墨烯（GO）具有独特的π键特性，因此被选作阳离子载体，以提高肥料抗流失能力并促进营养离子的有效释放。通过调节氧化石墨烯的界面性质，成功制备了波纹状氧化石墨烯（RGO）和皱缩状氧化石墨烯（CGO），并研究了它们与阳离子的相互作用以及对缓释性能的影响。所选用的最优动力学模型为材料设计提供了理论依据。结果表明，RGO-Zn1（锌/氧化石墨烯=16.7%）不仅能有效控制农业面源污染，还能促进高锌水稻的种植。本研究不仅为土壤改良和农业转型升级提出了创新解决方案，还为跨膜渗透过程中的阳离子-π相互作用机制提供了基础科学见解。
