近年来，新型二维过渡金属碳化物和碳氮化物MXene因其优异的结构和性能成为研究的热点。在此，我们研究了一种新的MXene基复合材料的合成，用于高效的染料吸附在污水处理中，通过一个简单的水热方法。对植酸（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）PO 4组分。此外，与MXene相比，PA-MXene复合材料对模拟染料MB和RhB的吸附性能增强，循环12次后对MB的吸附量仍保持在85%左右，显示出作为废水处理吸附材料的重要潜力。
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.
