Air pollution remediation using nanofibrous filters based on metal-organic frameworks (MOFs) prepared through electrospinning

Today, air pollution is one of the biggest problems of different societies due to the development of various industries around the world, especially in industrialized countries. Therefore, solving the problems of air pollution, the environment, disease, and toxicity caused by air pollution has attracted the attention of many researchers. This has led to the rapid development of nanotechnology in the field of air filtration. In this regard, various nanofibrous filters have been produced and studied for the absorption and removal of air pollutant particles. Nanofibers have a high potential for many environmental applications, including nanofilters and membranes, due to their high specific surface area, high porosity, high flexibility, and ease of production at different scales of different materials. Studies show that metal-organic frameworks (MOFs), as a new class of nanosorbents, are suitable for storing and separating gases, separating membranes, and various types of air pollution filters. Characteristics such as low density, adjustable pore size and their high surface area, selective adsorption of small molecules, and most importantly, reversible adsorption, make these compounds suitable for use in nanofibrous filters. In this paper, after introducing metal-organic frameworks and the performance of nanofibrous filters, a comprehensive review of the research performed on the nanofibrous filters and expressing the potential of metal-organic frameworks in improving the performance of nanofibrous filters in the filtration of air pollutants are given.
