Abstract
Abstract In recent years, metal organic frameworks (MOFs) have become emerging materials. Their applications in various fields are increasingly reported due to their special structure and excellent physical and chemical properties. Zeolitic imidazolate framework (ZIF) is a sub-system of MOF with good stability and similar structure to conventional type of zeolites. A variety of ZIF crystals have been obtained by adjusting metal ions as well as organic ligands. Through investigation, we found that the literature on gas sensing mainly focuses on the complexes of ZIF-8 and derivatives of ZIF-67, and there were also some reports on the application of other ZIF materials in gas response. In this paper, the reports of ZIF materials in the direction of gas sensing in recent years are summarized. By summarizing and considering the existing studies, it can help us better understand the current progress and limitations of ZIF materials in the development of gas sensing, and provide some possible development directions or ideas for the future development of ZIF materials.
