Materials with a high specific surface area including a porous structure have been widely researched due to the applicability in the adsorption of various organic dyes. However, further application of porous materials is limited by the complicated and expensive preparation process. Herein, a Sn-Ni coating with a polyporous structure is successfully prepared via a simple and high-efficiency electrodeposition approach in deep eutectic solvents (DESs). The prepared Sn-Ni coating exhibits a uniform polyporous structure with a diameter of 15 μm. Furthermore, the coating shows excellent adsorption capacity in the removal of acid grain black organic dyestuff. With the rise of preparation temperature from 85 to 105 °C, the electrochemical active surface area and the ratio of nickel increase, which further enhance dye adsorption capacity.
具有高比表面积且包含多孔结构的材料，因其在各种有机染料吸附方面的适用性而受到广泛研究。然而，多孔材料的进一步应用受到复杂且昂贵的制备过程的限制。在此，通过在深共熔溶剂（DESs）中采用简单高效的电沉积方法，成功制备了具有多孔结构的Sn-Ni涂层。所制备的Sn-Ni涂层呈现出直径为15μm的均匀多孔结构。此外，该涂层在去除酸性粒状黑色有机染料方面表现出优异的吸附能力。随着制备温度从85℃升高到105℃，电化学活性表面积和镍的比例增加，这进一步提高了染料吸附能力。
