Abstract In recent years, new family of two-dimensional (2D) transition metal carbide and carbonitrides-MXene has become critical materials due to their excellent structure and performance. Herein, we have investigated the synthesis of a new MXene-based composite material for efficient dye adsorption in sewage treatment, via a facile hydrothermal method. The characterization of the phytic acid (PA)-MXene composites showed that new rod-like Ti(OH)PO4 components appeared in the hydrothermal process. In addition, compared with the original MXene, the prepared PA-MXene composite exhibited enhanced adsorption properties for the model dyes MB and RhB, and the adsorption capacity of the PA-MXene composite on MB remained at about 85 % after 12 cycles, indicating important potential as an adsorbent material in wastewater treatment.

通过具有提高染料吸附能力的简便水热法合成自组装植酸-MXene纳米复合材料

摘要 近年来，新型二维（2D）过渡金属碳化物和碳氮化物家族——MXene因其优异的结构和性能而成为关键材料。在此，我们研究了一种新的基于 MXene 的复合材料，通过简便的水热法在污水处理中有效吸附染料。植酸 (PA)-MXene 复合材料的表征表明，在水热过程中出现了新的棒状 Ti(OH)PO4 组分。此外，与原始 MXene 相比，制备的 PA-MXene 复合材料对模型染料 MB 和 RhB 表现出增强的吸附性能，PA-MXene 复合材料对 MB 的吸附容量在 12 个循环后保持在 85% 左右，表明重要在废水处理中作为吸附材料的潜力。
