In the current paper, we reviewed a series of recent work on the development and sensing properties of copper oxide（Cu O）-functionalized quartz crystal microbalance（QCM） sensors towards hydrogen cyanide（HCN） detection. Firstly, we briefly introduced the toxicity and existing detection methods of HCN as well as the QCM technique. Then, we discussed the synthesis and characterization of different Cu O nanomaterials. Followingly, we presented the Cu O-functionalized QCM sensors using the Cu O nanomaterials as a sensing layer and QCM as a detection platform and their unique and excellent sensing properties towards HCN. The sensing mechanism of Cu O-functionalized QCM sensors to HCN was also discussed. Finally, a summary and outlook were made by discussing existing problems and future directions of related research and applications.
