With the frequent discharge of wastewater and leakage of oil accidents, it has gained much attention to treat oil and organic pollutants from water. Herein, a facile and environmentally friendly approach is presented to fabricate MgAlZn layered double hydroxide-coated stainless steel mesh (LDH-SSM) via hydrothermal method, which could be used to separate various oil/water mixtures due to its superhydrophilic and underwater superoleophobic property. The as-prepared mesh possesses selective separation performance for oil/water mixtures with separation efficiency higher than 99.2% and high water flux of ∼ 44.5 L m s under gravity-driven force. Such membrane shows an effective separation for oil/water mixtures and recyclability, as well as exhibit excellent superhydrophilicity, making it a prominent candidate for oily water remediation.
随着废水的频繁排放和石油泄漏事故的发生，从水中去除油类和有机污染物受到了广泛关注。在此，我们提出了一种简便且环保的方法，通过水热法制备镁铝锌层状双氢氧化物包覆不锈钢网（LDH-SSM），由于其超亲水性和水下超疏油性，可用于分离各种油/水混合物。所制备的网对油/水混合物具有选择性分离性能，分离效率高于99.2%，在重力驱动下具有约44.5 L m⁻² s⁻¹的高水通量。这种膜对油/水混合物具有有效的分离和可回收性，同时表现出优异的超亲水性，使其成为含油废水修复的突出候选材料。
