Engineering MXene@MOF Composites for a Wide Range of Applications: A Perspective

Abstract

This perspective presents an exploration of MXenes and metal−organic frameworks (MOFs) in diverse applications such as biomedical, electronics, and sensing based on their structural properties. The inherent design and synthesis flexibility, sharp edges, reactive oxygen species generation, and photothermal properties of MXenes might be exploited for further enhancement of these magic compounds' applicability. On the other hand, MOFs demonstrate potential in various fields like storage, delivery, and catalysis owing to their large surface/volume ratio and porosity. Despite certain limitations, including poor electrical conductivity of MXenes, recent studies suggest that MXene@MOF composites can address the major challenge, leading to the development of highly sensitive and selective sensors for a range of chemical and biological species. The perspective underscores that the amalgamation of MXenes and MOFs can yield a synergetic effect, thereby boosting the inherent properties of these materials in antimicrobial and sensing applications. Moreover, with the rapid progression of nanotechnology, MXene@MOF composites are expected to witness increasing usage in various sectors, such as energy and electronics. Nonetheless, further studies are required to fully understand the potential human health and environmental impacts of these materials, and several obstacles, including scalability of manufacturing processes, stability, and repeatability of properties, must be addressed. MXene@MOFs present a compelling area of research with immense potential for transformative applications across numerous sectors.
