AB  - Ti(3)C(2)T(x) MXene has attracted considerable interest as a new emerging 
      two-dimensional material for environmental remediation due to its high adsorption 
      capacity. However, its use is greatly limited by its poor mechanical properties, 
      low processability and recyclability, and the low dispersity of such powder 
      materials. In this work, a porous adsorbent (C-CMP) containing cellulose 
      nanocrystals (CNC), Ti(3)C(2)T(x) MXene and polyvinyl alcohol (PVA) was prepared 
      by a simple and environmentally-friendly foaming method. Glutaraldehyde was used 
      as crosslinker to improve the mechanical properties and boost the adsorption 
      efficiency of methylene blue (MB) molecules. Fourier transform infrared (FT-IR), 
      elemental analysis (EDX) and thermogravimetric analysis (TGA) further confirmed 
      that the preparation of the C-CMP foam and cross-linking reaction were 
      successful. Scanning electron microscope (SEM) indicated that the macropores were 
      distributed homogeneously. The adsorption experiment showed that maximum 
      adsorption capacity of MB can reach 239.92 mg.g(-1) which was much higher than 
      anionic dye (methyl orange, 45.25 mg.g(-1)). The adsorption behavior fitted well 
      with the Langmuir isotherm and pseudo-second-order kinetic models. Thermodynamic 
      analysis indicated that the adsorption process was spontaneous and endothermic. 
      Based on FT-IR, EDX and X-ray photoelectron spectroscopy (XPS) analysis, the 
      adsorption mechanism between C-CMP and MB molecules was attributed to 
      electrostatic interaction.
