When MOFs meet wood: From opportunities toward applications

Metal-organic frameworks (MOFs) have drawn widespread atten-tion owing to their structural diversity and multifunctionality. How-ever, further practical applications of MOFs are limited by their powdered crystalline state. Compounding with self-supporting porous materials with good processibility can effectively fix the powdered MOFs. Wood is highly compatible with MOFs because of its natural multidimensional channel structure and excellent me-chanical stability. MOF particles can be uniformly loaded onto the wood channel via physical adsorption, hydrogen bonding, or react-ing with hydroxyl and carboxyl groups in the fibers. Ultimately, MOF@wood composites with new functions are synthesized, showing great potential in the direction of interdisciplinary research. This review summarizes the fabrication strategies and functional applications of representative MOF@wood composites and discusses their development prospects and potential advan-tages. In conclusion, it is expected to provide systematic research ideas for the future development of MOF@wood composites.
