A single-step gas-phase reaction for synthesizing zinc oxide and carbon nanoparticle composite

摘要

Zinc oxide and carbon nanoparticle composite could be prepared using a single-step gas-phase reaction within a quartz tube reactor. Effect of nitrogen flow rate in a range of 1, 2 and 3 l/min on size and morphology of the composites was experimentally investigated at a temperature range of 900 to 1,100 °C, Zn:C:Fe molar ratio of 10:10:1 and oxygen flow rate of 20 ml/min. Scanning electron microscopic analysis revealed that the fabricated nanostructures consist of carbon nanotubes decorated with zinc oxide particles. The increase in the flow rate of nitrogen carrier gas could affect on the morphology and yield of zinc particles existing in the prepared composite.
