The formation of 1-D and 3-D transition metal oxide nanostructures on molybdenum, iron, and tungsten probes inserted in a counterflow flame is studied experimentally. The unique thermal profile and chemical composition of the generated flame tends to convert almost pure bulk (99.9%) transition metal materials into I-D and 3-D architectures. The synthesized Mo, Fe, and W oxide structures exhibit unique morphological characteristics. The application of Mo probes results in the formation of micron size hollow and solid Mo-oxide channels. The use of W probes results in the synthesis of 1-D carbon-oxide nanowires. The formation of iron-oxide nanorods is observed on iron probes.
