We prepared two-dimensional (2D) stack-structured magnetic iron oxide (Fe₃O₄) nanoparticle anchored titanium carbide (Ti₃C₂T_x) MXene material (Ti₃C₂T_x/Fe₃O₄). It was used as a potential adsorbent to remove carcinogenic cationic dyes, such as methylene blue (MB) and rhodamine B (Rh B), from aqueous solutions. Ti₃C₂T_x/Fe₃O₄ exhibited maximum adsorption capacities of 153 and 86 mg g⁻¹ for MB and Rh B dyes, respectively. Batch adsorption experimental data fits the Langmuir model well, revealing monolayer adsorption of MB and Rh B onto the adsorption sites of Ti₃C₂T_x/Fe₃O₄. Additionally, Ti₃C₂T_x/Fe₃O₄ showed rapid MB/Rh B adsorption kinetics and attained equilibrium within 45 min. Moreover, Ti₃C₂T_x/Fe₃O₄ demonstrated recyclability over four cycles with high stability due to the presence of magnetic Fe₃O₄ nanoparticles. Furthermore, it exhibited remarkable selectivities of 91% and 88% in the presence of co-existing cationic and anionic dyes, respectively. Given the extraordinary adsorption capacities, Ti₃C₂T_x/Fe₃O₄ may be a promising material for the effective removal of cationic dyes from aqueous media.
