Oily wastewater has caused serious damage to the human health and ecological environment. It is urgent to develop novel materials for high performance oil/water separation. Porous melamine sponges (MS) are considered as an ideal matrix material for oil/water separation. Herein, molybdenum sulfide (MoS₂) modified with tannic acid (TA) and octadecylamine (ODA) was attached to MS framework via a facile dip-coating method. This novel and eco-friendly MS@(MoS₂@ODA) sponge displays superior superhydrophobicity (WCA = 156.2°) and oil/water separation ability (absorption capacity = 113–145 g g⁻¹). MoS₂@ODA not only enhances surface roughness of MS framework, but also raises its specific surface area, causing an increase in the oil adsorption capacity of MS. Moreover, the composite sponge exhibited excellent chemical and mechanical stability. It is envisioned that this work can demonstrate a facile synthesis strategy for producing environmental friendliness MS with stable superhydrophobicity for high-efficient oil/water separation.

环保易用硫化钼改性超疏水三聚氰胺海绵用于油水分离

含油废水已对人类健康和生态环境造成严重危害。开发用于高性能油水分离的新型材料迫在眉睫。多孔三聚氰胺海绵 (MS) 被认为是用于油水分离的理想基质材料。在此，通过简便的浸涂法将用单宁酸 (TA) 和十八胺 (ODA) 改性的硫化钼 (MoS _{2 ) 连接到 MS 骨架上。}这种新颖且环保的 MS@(MoS ₂ @ODA) 海绵表现出优异的超疏水性 (WCA = 156.2°) 和油/水分离能力 (吸收能力 = 113–145 g g ⁻¹ )。_二硫化钼@ODA 不仅提高了 MS 骨架的表面粗糙度，还提高了其比表面积，导致 MS 的油吸附能力增加。此外，复合海绵表现出优异的化学和机械稳定性。预计这项工作可以展示一种简便的合成策略，用于生产具有稳定超疏水性的​​环境友好型 MS，用于高效油水分离。
