Abstract
In a carbothermal reduction process, it has been proved theoretically and experimentally that a critical limit of oxygen with addition to a conventional Ar gas is necessary to get ZnO nanostructures. More than 1Â ppm of oxygen was required to fabricate ZnO nanowires. Related local thermodynamics and kinetics were considered and discussed. This oxygen-assisted carbothermal reduction process enables an evolution of not only ZnO nanowires but also interesting nanorods and nanosheets in series with controlling oxygen partial pressure in the range of 10â6-10â2.
