Electrospun Metal–Organic Framework Nanofiber Membranes for Energy Storage and Environmental Protection

Metal–organic frameworks (MOFs) are attractive in many fields due to their unique advantages. However, the practical applications of single MOF materials are limited. In recent years, a large number of MOF-based composites have been investigated to overcome the defects of single MOF materials to broaden the avenues for the practical applications of MOFs. Among them, MOF-based hybrid nanofiber membranes fabricated by electrospinning combine the advantages of polymer nanofibers and inorganic porous materials, receiving extensive attention and development in energy storage and environmental protection. This review systematically summarizes the recent progress of MOF-based hybrid nanofiber membranes prepared by electrospinning from the perspectives of preparation and application. Firstly, two main methods for preparing MOF/polymer nanofibrous membranes are discussed. Next, the applications of MOF/polymer nanofibrous membranes in energy storage and environmental protection are summarized at length. Finally, to fully tap the potential of MOF-based nanofiber membranes in more fields, the current challenges are proposed, and future research directions are discussed.Graphical Abstract
