Synthesis and characterization of novel vanadium dioxide nanorods

摘要

Novel vanadium dioxide nanorods were fabricated via a surfactant-assisted hydrothermal method at 180 degreesC for 48 h in the presence of cetyltrimethylammonium bromide (CTAB). The self-assembled samples were characterized by XRD, SEM, TEM, HRTEM and FT-IR. The results show that the products are nanorods, which are pure B phase vanadium dioxide with high crystallinity. The obtained nanorods have diameters of 40-60 nm with lengths up to 1-2 um. The probable formation mechanism of vanadium dioxide is also discussed. (C) 2004 Elsevier Ltd. All rights reserved.
