“…The intimate contact between Bi 2 WO 6 nanosheets and Ti 3 C 2 T x is beneficial for the interfacial charge transfer in the composites and thus the photoactivity enhancement towards CO 2 reduction as compared to bare Bi 2 WO 6 . In addition, different MXenes-based composites have also been fabricated through in situ growth of semiconductors on the 2D surface of MXenes, such as Ti 3 C 2 T x -CdS, [70,71] Ti 3 C 2 T x -ZnS, [72] [73] Ti 3 C 2 T x -ZnIn 2 S 4 , [74] Ti 3 C 2 T x -BiOBr, [75] Ti 3 C 2 T x -BiOCl, [76] [77] Nb 2 CT x -TiO 2 , [34] Nb 2 CT x -Bi 2 WO 6 , [78] Mo 2 CT x -CdS, [79] etc. [80][81][82][83][84][85][86] (detailed information can be found in Table 1).…”

MXenes are becoming a worthy contender for boosting the efficacy of semiconductor photocatalysts because of their rich surface and electronic properties, which is exemplified to be a dynamic yet open‐ended exploration of the materials space. Herein, the promise that MXenes hold for photocatalytic applications is elucidated by presenting the various roles of MXenes in the preparation of composite photocatalysts and enhancing their activity and stability. A specific focus is put on the key issues that should be taken into account when utilizing the specific function of MXenes and the strategies to deliver the great potential of MXenes into better play. The discussion is based on different aspects closely related to the flexible surface and electronic features of MXenes, including their morphology control, stability issue, and electronic structure mutability with the purpose to present an objective and comprehensive scenario of MXenes for photocatalysis. Finally, some noteworthy research directions for the future development of MXenes‐based photocatalytic systems are outlined and prospected. This review is expected to provide a useful scaffold for the rational design and synthesis of efficient and stable MXenes‐based photocatalysts by objectively understanding and taming the functional vitality of MXenes.

Discovered in 2011, MXene becomes a most recent and active member of two-dimensional materials. Since then, the landscape of MXene grows significantly and now more than 30 different MXenes were obtained experimentally. Though most of the efforts are contributed to Ti-MXenes which have the highest level of maturity of the synthetic technology and productivity, in recent years, new-MXene systems with Molybdenum (Mo), Vanadium (V), and Niobium (Nb) as the transition metals demonstrated their unique properties and applications. The development of new-MXenes not only expands the synthetic methods and applications of MXenes but also faces new challenges. Therefore, a timely summary of Mo-, V-and Nb-MXenes will be extremely beneficial. Here, the synthetic methods of the selected new-MXenes are summarized and their most recent applications are highlighted to provide an outlook for the future development of MXenes.
