Abstract With the emergence of two‐dimensional (2D) materials analogous to graphene, transition metal carbides and carbonitrides with unique desirable characteristics known as MXenes have turned out be a hot research topic. Recent studies increasingly focus on structure–property relationships their hybrid formations other materials. The exfoliation delamination using various agents is gaining attention, while application in functional composites presents another exciting direction. However, multi‐layered MXene into few‐layered nanosheets bio‐based remains underexplored. In this study, tannic acid (TA) employed bio‐exfoliating agent delaminate Ti 3 C 2 T x MXene, optimizing ratio TA achieve efficient dye adsorption. MXene/TA demonstrated maximum adsorption capacity 187.264 mg/g removal efficiency 93.69% for methylene blue (MB) water, accordance Langmuir isotherm model. Furthermore, MB caused coagulate floccules, enabling easy via filtration. study highlights trifold role delaminating, antimicrobial, adsorption‐enhancing agent, creating multifunctional MXene‐tannic system. It introduces new class effective applications water purification.
