Recent Advancement in Emerging MXene‐Based Photocatalytic Membrane for Revolutionizing Wastewater Treatment

Abstract MXene‐based photocatalytic membranes provide significant benefits for wastewater treatment by effectively combining membrane separation and photocatalytic degradation processes. MXene represents a pioneering 2D photocatalyst with a variable elemental composition, substantial surface area, abundant surface terminations, and exceptional photoelectric performance, offering significant advantages in producing high‐performance photocatalytic membranes. In this review, an in‐depth overview of the latest scientific progress in MXene‐based photocatalytic membranes is provided. Initially, a brief introduction to the structure and photocatalytic capabilities of MXene is provided, highlighting their pivotal role in promoting the photocatalytic process. Subsequently, in pursuit of the optimal MXene‐based photocatalytic membrane, critical factors such as the morphology, hydrophilicity, and stability of MXenes are meticulously taken into account. Various preparation strategies for MXene‐based photocatalytic membranes, including blending, vacuum filtration, and dip coating, are also discussed. Furthermore, the application and mechanism of MXene‐based photocatalytic membranes in micropollutant removal, oil–water separation, and antibacterial are examined. Lastly, the challenges in the development and practical application of MXene‐based photocatalytic membranes, as well as their future research direction are delineated.
