Obtaining uniform WO3 nanoparticles on a gram scale within 120 seconds

Abstract

WO₃ nanoparticles were synthesized on a gram scale within 120 seconds via a dynamic magnetic field transportation (DMFT) technique. The size control of WO₃ nanoparticles was achieved by adjusting the furnace pressure. The final WO₃ nanoparticles exhibited a relatively uniform size distribution (d = 62.1 ± 18.8 nm), suggesting the variance was very small. The WO₃ nanoparticles also possessed the property of absorbing ultraviolet light ranging from 200 nm to 400 nm. The as-synthesized uniform WO₃ nanoparticles hold broad application prospects towards various fields such as ultraviolet shielding and as a nanoscale tungsten carbide (WC) precursor.
