Synthesis of MnVO nanoflakes via simple hydrothermal process

Abstract

A single phase of monoclinic MnV₂O₆ nanoflakes was prepared by a hydrothermal process at 180°C for 18 h, using Mn (CH₃COO)₂·4H₂O and NH₄VO₃ as starting materials and using acetic acid to adjust the pH value of the reaction solution. The as-prepared samples were characterized by field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM). X-ray photoelectron spectrum (XPS) measurements further confirm the component of MnV₂O₆. Results indicated that the products consisted of a large quantity of compact accumulated nanoflakes, with average width of 0.85 ?m, thickness of 100 nm and lengths up to 1.7 ?m.
