Abstract

Abstract

Aiming to solve the preparation problems of complex, high cost and low efficiency of the existing vanadium pentoxide (V₂O₅) nanomaterials, especially their nanowire nonwovens, herein a one-step hydrothermal method for efficient preparation of V₂O₅ nanowire nonwoven was provided and the relevant mechanism was preliminarily studied afterwards. In comprehensive consideration of product quality and economy, the optimized hydrothermal reaction conditions are 180～200 ℃, 18～24 h, the concentration of hydrochloric acid in the system is 1%～3%, and the concentration of ammonium metavanadate (AMV) is 1%～3%. The optimized nanowire cloth has a thickness of 0.1～1 mm with inner wire diameter of 50～100 nm. Through the optimization of preparation conditions, the resulting V₂O₅ nanowire nonwoven shows good flexibility, structural uniformity and adjustable wrinkles.
