Frontier Progress and Fundamental Hurdles: A Perspective on the Evolution of Metal–Organic Framework/Wood Composites

Metal-organic frameworks (MOFs), as a class of advanced porous materials with tunable functionalities, have demonstrated exceptional application potential across various fields. Wood, a natural and green material featuring hierarchical pore structures and abundant functional groups, offers an ideal three-dimensional structural scaffold for the immobilization and functionalization of MOFs. From the perspective of "wood-based carrier design", this perspective systematically reviews the latest research progress on MOF/wood composites in multiple cutting-edge fields. Furthermore, it provides an in-depth analysis of the current bottlenecks and challenges facing MOF/wood composites from application, material, and interface perspectives, along with several insightful recommendations. In summary, this perspective is expected to offer thought-provoking research directions for the future development of MOF/wood composites.
