“…Generally, the surfactant micellar solutions are isotropic, thermodynamically stable system in which the oil phase is dispersed as nano-sized droplets surrounded by a monolayer of surfactant molecules in the continuous water phase [126]. In which the surfactant micelle is more popular to synthesized 1-D materials.…”

One-dimensional (1-D) structure semiconducting metal oxides, such as nanorods, nanowires, and nanotubes have attracted scientists worldwide because they have many potential applications, including catalysts, photocatalysts, photoemission, solar cells, nanogenerators, field emission, lasers, building block in nanoelectronic devices, and gas sensors. Additionally, 1-D materials have two quantum-confined directions while still leaving one unconfined direction for electrical conduction, making them suitable for resistive-type gas sensor applications. The resistive-type gas sensors operate based on the change in electrical conductance of sensing materials upon gaseous molecules exposures. One-dimensional structures of various semiconducting metal oxides have been fabricated for gas sensors and the applications include CuO, Sn0 2 , Ti0 2 , ZnO and W0 3 . The 1-D structured materials can be fabricated by a "top-down" approach, using advanced nanolithographic techniques, such as electron-beam, focusedion-beam writing, proximal probe patterning, X-ray or extreme-UV, and nanoscale spacer lithography. Otherwise they can be fabricated by "bottom-up" routes, including catalytic growth process, thermal evaporation, thermal chemical vapor deposition (CVD), template assisted route, and hydrothermal or solution methods. This chapter provides brief information about the synthesis and characterization of 1-D semiconducting metal oxides. In addition, the gas sensors application of 1-D materials is introduced in terms of sensitivity, selectivity, response time, recovery time, and sensing mechanisms.
