This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanomaterials have attracted extensive interest due to their unique structure and excellent properties compared with their bulk counterparts. To obtain nanodevices with controlled properties, it is prerequisite to synthesize nanostructured materials with designed architecture. In this work, low (one- and two- ) dimensional nanomaterials with controlled structures have been synthesized and characterized based on chemical vapour deposition strategy. Our research targets cover one-dimensinoal hollow, solid, and solid @ hollow heterostructural nanomaterials including carbon nanotubes (CNTs), nitrogen-doped carbon nanotubes (NCNTs), SnO2 nanowires, Mo doped-SnO2 nanowires, Sn nanowires encapsulated in CNTs (Sn@CNTs), and two-dimensional Mo2S3 nanopetals. Dependence of product morphology, composition and phase structure on the synthesis conditions has been systematically investigated by changing temperature, growth time, gas flow, external atom doping, catalyst and employed substrate, to get insight into the correlation between the structure control and growth conditions of the products and their growth mechanism as well. High quality CNTs and NCNTs with uniform size were synthesized on carbon paper and Si wafer by introducing thin iron sputtering film as catalyst. High nitrogen content up to 10.4 at% was reached in the NCNTs. Controlled growth of SnO2 and Mo-doped SnO2 nanowires was obtained on different substrates including carbon paper, stainless steel and Cu to meet substrate requirements for practical applications. It was found that Mo doping could significantly improve the corrosion resistance of the SnO2 nanowires. Core-shell heterostructures of Sn nanowires @ CNTs were produced on carbon microfibers, stainless steel and Cu substrates. Rational control on the thickness and nature of the carbon shell of the heterostructures on carbon microfibers was realized by modulating growth parameters and introducing extra catalyst. Multi-generation Sn@CNTs were obtained by exploring SnO and SnO2 as starting materials. On the metallic substrates, Sn-alloy@CNT nanostructures were obtained. In another way, SnCo alloy nanowires @ CNTs with readily controlled Co content were achieved by introducing cobalt-contained precursor. Non-catalytic and catalytic growth of two-dimensional Mo2S3 nanopetals was investigated on carbon microfibers. Without catalyst, the nanopetals with high density were only obtained in a narrow range of the precursor concentration. With Au catalyst, uniform nanopetals with steady high density could be achieved in a wide range of the precursor concentration. Morphology, composition and phase structure of the nanostructures were characterized and analyzed by electron microscopy, X-ray diffraction, energy-dispersed spectroscopy and Raman spectroscopy.

Download or read book One Dimensional Nanostructure and Sensing Applications written by and published by . This book was released on 2016 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: The key challenge for a nanomaterial based sensor is how to synthesize in bulk quantity and fabricate an actual device with insightful understanding of operational mechanisms during performance. I report here effective, controllable methods that exploit the concepts of the "green approach" to synthesize two different one-dimensional nanostructures, including tin oxide nanowires and carbon nanotubes. The syntheses are followed by product characterization and sensing device fabrications as well as sensor performance understanding at the molecular level. Sensor-analyte response and recovery kinetics are also presented. The first part of the thesis describes bulk-scale synthesis and characterization of tin oxide nanowires by the molten salt synthetic method and the nanowire doping with antimony (n-types) and lithium. The work builds on the success of using n-doped SnO2 nanoparticles to selectively detect chlorine gas at room temperature. Replacing n-doped nanoparticles with n-doped nanowires reduces the number of inter-particle electron hops between sensing electrodes. The nanowire based sensors show unprecedented 5 ppb detectability of corrosive Cl2 gas concentration in air. At the higher range, 10 ppm of Cl2 gas leads to a 250 fold increase in the device resistance. During sensor recovery, FT-IR studies show that dichlorine monoxide ( Cl2O) and chlorine dioxide (ClO2) are the desorbing species. Long term stability of devices is affected by lattice oxygen vacancies replaced by chlorine atoms. Bulk-scale synthesis of multiwall carbon nanotube (MWCNTs) was achieved by a novel inexpensive synthetic method. The green chemistry method uses the non-toxic and easy to handle solid carbon source naphthalene. The synthesis is carried out by simply heating naphthalene and organometallic precursors as catalysts in a sealed glass tube. Synthesis at 610o C leads to MWCNTs of 50 nm diameter and lengths exceeding well over microns. MWCNT doping is attempted with nitrogen (n-type) and boron (p-type) precursors. Palladium nanoparticles decorated on as-synthesized MWCNTs are employed for specific detection of explosive hydrogen gas with concentrations far below the explosive concentration limits. During performance, the sensor exhibits abnormal response behaviors at hydrogen gas concentrations higher than 1%. A model of charge carrier inversion, brought about by reduction of MWCNT by hydrogen molecules dissociated by Pd nanoparticles is proposed.
