摘要(Abstract)：

为了解决光催化剂在光生电子与空穴中分离效率低且难以回收利用的问题，以钛碳化铝(Ti₃AlC₂)为原料，通过LiF+HCl刻蚀法、共沉淀法、溶剂热法和异种电荷静电自组装，获得具有磁分离性能的新型异质结光催化材料AMHNTs/TiO₂-Ti₃C₂T_x(H&M)，对其进行结构表征，并选取偶氮类染料甲基橙 (MO)为污染物模型，考察模拟太阳光下H&M的降污性能及降解机理。结果表明：制备的异质结H&M融合了二维层状与一维管状的结构特征，提高电子的传导输送，具有良好的光催化活性和磁回收性，且对MO有较好的降解性能，为构筑新型磁性无机异质结光催化材料和染料的光降解提供有价值的参考。
