Abstract

MnV 2O 6 nanobelts were prepared from the reaction between MnCl 2·4H 2O and NH 4VO 3 solutions under hydrothermal conditions in the presence of nitric acid (1%, v/v) as an acidifying agent. The synthesized products were characterized by XRD, FESEM, TEM, SAED, HRTEM and XPS analytical techniques. SAED and HRTEM confirm the single-crystalline nature of MnV 2O 6 nanobelts. The nanobelts of MnV 2O 6 are obvious, with an average diameter of 110 nm, 10 nm in thickness and several tens of micrometers in length. The effect of pH, reaction time, and temperature on the morphologies of the resulting products has been investigated. The key factors to control the morphology and a possible formation mechanism were discussed.
