This study addresses the critical issue of removing toxic dyes from industrial wastewater to protect the environment and human health. To address this challenge, a bio‐based composite hydrogel was synthesized using gamma irradiation, 20 kGy, incorporating multiwalled carbon nanotubes@pectin/κ‐carrageenan/polyacrylic acid (MWCNTs PC/KC/PAAc) for removing methylene blue (MB) dye from aqueous solutions. The prepared composites underwent characterization through Fourier‐transform infrared spectroscopy, x‐ray diffraction, and thermogravimetric analyses. Brunauer–Emmett–Teller analysis demonstrated a significant increase in surface area upon the addition of MWCNTs. Specifically, the surface area increased from 342.5 m2 g−1 for PC/KC/PAAc to 689.5 m2 g−1 when 0.175&#x02009;wt% of MWCNTs were added. Also, scanning electron microscopy and atomic force microscopy were utilized to examine the surface topography of PC/KC/PAAc and MWCNTs@PC/KC/PAAc. The results reveal that at 0.175&#x02009;wt% of MWCNTs, there was a more uniform surface topography with well‐distributed MWCNTs within the matrix. In the adsorption study of MB dye, it was found that the highest MB removal efficiency was achieved at pH&#x02009;11, with values of 68.21% and 96% for PC/KC/PAAc and MWCNTs@PC/KC/PAAc, respectively. Furthermore, upon studying the effect of MWCNTs (%), the results showed that the removal (%) of PC/KC/PAAc was 68.21&#x02009;±&#x02009;1.02%, and this percentage increased rapidly with the addition of MWCNTs, reaching a maximum of 96&#x02009;±&#x02009;0.85% when 0.175 (wt%) of MWCNTs was added. Isotherm and kinetic modeling demonstrated that MB adsorption follows the Freundlich isotherm for PC/KC/PAAc and the Redlich–Peterson isotherm for MWCNTs@PC/KC/PAAc, both following a pseudo‐second‐order kinetics model. In addition, from AFM data, after MB removal, the height increased significantly from 322&#x02009;nm for PC/KC/PAAc to 810&#x02009;nm for MWCNTs@PC/KC/PAAc (0.175&#x02009;wt%), indicating a substantially higher adsorption of MB by MWCNTs@PC/KC/PAAc.

“…9,10 It is important to eliminate different organic dyes from contaminated water because a large volume of dye-containing wastewater is generated daily from various industries. 11 Since most organic dyes are stable to oxidation and light, degradation of them is usually very difficult. Moreover, the quality and color of water can be significantly dependent on the presence of organic dyes.…”

MXene has indeed gained significant attention in recent years as a promising photocatalyst for various applications, including photocatalytic degradation of pollutants. MXene possesses several unique physical and chemical properties that make it suitable for such applications, including its uniform planar structure, strong metal conductivity, effective functional groups, and numerous derivatives. These properties contribute to the excellent photodegradation performance and long‐term stability exhibited by MXene‐based photocatalysts compared to other photocatalysts. MXene‐based composites, which are formed by incorporating MXene with other materials, demonstrate even better photodegradation activity due to their abundant active sites and porous structure. One crucial factor influencing the photodegradation performance of MXene‐based photocatalysts is the presence of active functional groups on the surface of MXene. These functional groups play a significant role in the photocatalytic process and contribute to the overall efficiency of the catalyst. To provide a broader understanding of MXene‐based photocatalysts, the physicochemical properties of MXene are briefly described in this review. This includes its structural characteristics, electrical conductivity, and the presence of functional groups. This review also investigates the physical and chemical synthesis routes for preparing MXene, both in its natural state and as composites with other materials. These synthesis methods are essential for tailoring the properties of MXene‐based photocatalysts to meet specific requirements. Finally, the review discusses future work and challenges in MXene‐based photocatalysis. This field holds great promise for addressing environmental concerns and improving the degradation of organic compounds. However, further research is needed to optimize the synthesis methods, enhance the photocatalytic efficiency, and explore the practical applications of MXene‐based photocatalysts.
