Effects of Reductant on Physical Properties and Formation of Vanadium Oxide Compounds Prepared by Hydrothermal Route

摘要

Vanadium oxide nanostructures were successfully synthesized by hydrothermal process using V_2O_5 as a starting source material. The process was conducted at 120°C for 48 h using different reductants including n-butanol and acetylacetone. The essential physical properties of as-synthesized products were characterized by XRD, FT-IR spectroscopy, SEM and TEM. The XRD and Raman results revealed that the crystalline structure and phase of the samples are highly dependent on the reductant types. The SEM images enclose that as-prepared samples possess different morphologies depending on different reactant. The phase transformation from V_2O_5 to VO_2 can be also carried out by this process with assistance of these reactants.
