Investigating Organic Vapor Sensing Properties of Composite Carbon Nanotube-Zinc Oxide Nanowire

The low operating temperature of nanowire gas sensors along with their high surface-to-volume ratio are two factors that make more practical. In this paper, the growth ZnO nanowires on a vertically aligned CNT forest is reported. utilized method for was rapid microwave-assisted hydrothermal route, which facilitates low-temperature and ultra-fast fabrication. Organic vapor sensing properties fabricated samples were studied in response to different alcoholic vapors at wide range 25 300 °C. Enhancement observed increasing temperature. Moreover, effect length organic CNT-ZnO investigated. Results proved long wires exhibit higher sensitivity examined analytes. Different attained via variation microwave exposure time power. Fabrication parameters selected based numerous runs. synthesized each distinct run calculated SEM micrographs samples.
