Synthesis and characterization of single-crystal MnV2O6 nanobelts

MnV2O6 nanobelts were prepared from the reaction between MnCl2·4H2O and NH4VO3 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 MnV2O6 nanobelts. The nanobelts of MnV2O6 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.
