英文摘要: This project would explore design, preparation, tailoring of metal oxide nanostructures (MONs) including copper oxide (CuO) and their application as sensing layer for gases including HCN. Major contents would include: (1) Design, preparation, modification, optimization and characterization of MONs including CuO; (2) Preparation of MONs (including CuO) gas sensors and testing of their sensing properties; (3) Sensing mechanism-study of the interaction between MONs (including CuO) and gases such as HCN; (4) Design, construction and testing of prototype devices that use the MONs (including CuO) sensors. Throung investigation, the intrinsic interaction between MONs (including CuO) and gases such as HCN will be unveiled, and sensing mechnisms will be proposed. The sensing characteristics will be improved via optimizing the composition, structure and morphology of the nanomaterials and the thickness and frame structure of the sensing layer. Among them, the CuO QCM sensors will reach the lowest detection limt of ﹤0.1ppm and response time of ﹤5s,and have characteristics of high sensitivity, good selectivity, high stability and good repeatbility. Finally prototype devices will be desinged and given.
