ABSTRACT
Volatile organic compounds (VOCs) are a pronounced source of indoor air contamination. These molecules have significantly affected human health and the surrounding environment when the concentration increases above the threshold limit value. Therefore, monitoring and detecting these harmful gases is an important issue. Intensive research efforts have being devoted to the design of new sensor materials to detect these harmful gases in the last few years. The metal-organic framework (MOFs) based sensor becomes a promising candidate for sensing applications due to its unique physicochemical properties and flexible nature. The sensing activity of a sensor relies on the capacity of the material used in the sensor. In this context, tailoring of physiochemical behavior of MOFs and their composites can create promising tools. The scientific community paid attention to the development of efficient, durable, and flexible VOC sensors using such tailored MOFs and their hybrids. MOF-based nanocomposites were found to be promising candidates for VOC sensing. Numerous strategies for the improvement of sensing efficiency have been reported which include potential MOF synthesis, nanocomposite formation, and device fabrication. The present chapter highlights the fundamentals of MOF-based sensors for VOC detection and outlines the recent development in MOF-based electronic sensing materials and chemiresistors.
