Metal-organic frameworks(MOFs)are a large class of crystalline porous materials that composed of organic li-gands and metal ions,of which zeolitic imidazolate frameworks(ZIFs)are a broad classification.The most well-known ZIF-like material is ZIF-8 crystals,which have been the subject of extensive research for decades.ZIF-8 crystals have been synthesized under various conditions for application in the fields of sensing,drug delivery,and catalysis.This paper provides a brief introduction to the preparation methods,formation processes,and formation mechanisms of ZIF-8 crystals in different media,and then explains the effects of different precursor conditions(type of Zn2+,ratio of raw materials,and type of solvent)on ZIF-8 crystals in terms of formation mechanisms.Subsequently,current reports on the application of ZIF-8-based chemiresistive gas sensors,elec-trochemical,fluorescent and colorimetric sensors are also summarized.Hopefully,ZIF-8 crystals with good cat-alytic properties will be obtained based on rational design for promoting the application in different fields of the sensors.
