MXene (Ti3C2Tx) film prepared by vacuum-assisted filtration (V-MXene film) is the most common 2D MXene macroscopic assembly with ultra-high electrical conductivity, tunable interlayer space, diverse surface chemical properties, favorable mechanical properties and so on, showing great commercial value in the fields of energy storage, electromagnetic interference shielding and actuators and so on. This paper focuses on the preparation, properties and applications of V-MXene film, objectively reviews and evaluates the important research progress of V-MXene film in recent years and analyzes the main problems at present. In addition, the development direction and trend of V-MXene film in the future are prospected from the aspects of preparation, property control and application fields, which provide guidance and inspiration for the further development of functional MXene-based films and make contributions to the progress of MXene technology.
As a kind of efficient adsorptive material, hydrogel has a wide application prospect within different fields, owing to its unique 3D network structures composed of polymers. In this paper, different synthetic strategies, crosslinking methods and their corresponding limitations and outstanding contributions of applications in the fields of removing environmental pollutants are reviewed to further provide a prospective view of their applications in water resources sustainability. Furthermore, the applications within the biomedical field, especially in wound dressing, are also reviewed in this paper, mainly due to their unique water retention ability, antibacterial ability, and good biocompatibility. Finally, the development direction of hydrogels in the fields of environmental remediation and biomedicine were summarized and prospected.

Gas molecules and volatile compounds in the air affect product purity and health. Because of increasing demand for better quality of life and health in industrial and general environments, timely detection of abnormal gas releases and poisonous compound volatilization is essential. Luminescence metal-organic frameworks (LMOFs) are materials with tunable pore sizes, defined structures, and luminescence properties, which have been widely reported as sensor materials for detecting various compounds. Here, luminescence mechanisms of LMOFs are reviewed and interactions between the host and guest molecules are explained at the molecular level. On the basis of these relationships, state-of-the-art LMOF-based sensors for various common gas molecules (including H 2 O, O 2 , CO x , and NO x ) and volatile organic compounds (VOCs) are further described in depth. This review may benefit the further development of LMOFs and accelerate their practical application in various sensor combinations.
