摘　　要：As a typical strongly correlated transition oxide,vanadium dioxide(VO_(2))based nanomaterials have drawn many research attentions these years due to the giant metal-to-insulator phase transition(MIPT)at around 68℃.However,due to the complexities of the V-O system and interplays between various vanadium oxide phases,the synthesis of high-quality VO_(2)nanopowders is still fraught with many challenges,especially in air atmosphere.In this paper,we report a novel air atmosphere available liquid-shielding synthesis method for thermochromic VO_(2)nanoparticles,by using low-eutectic molten-salt(LiCl-KCl)as the liquid-state air-insulation medium at elevated temperature and high-pressure pressed VOSO_(4)-KCl pillars immersed in these liquid salts as the precursor.Small amounts of glucose are added to introduce a slight reductive environment,and well dispersed VO_(2)nanoparticles with excellent ther-mochromic properties can be directly synthesized at an ultra-low temperature of 375℃.This feasible and atmosphere-available mass-production method is rarely reported in the related fields,which may provide a novel protocol strategy for the synthesis of high performance thermochromic VO_(2)and other functional oxide powders.
