Abstract

Abstract

For the spray pyrolysis process, the device was optimized by computational fluid dynamics (CFD) method. Through comparison and analysis, the heat preservation optimization was adopted for the inlet and outlet sections of the tubular furnace to improve the uneven temperature and velocity field distributions. An ultrasonic spray pyrolysis device was designed and set up, and the influences of precursor solution, precursor concentration and pyrolysis temperature on the particle size and morphology of the products were investigated through experiments. The results show that the main products of the ultrasonic pyrolysis of vanadyl oxalate solution are V₂O₃, while the pyrolysis products of vanadyl sulfate and vanadyl dichloride are blue black VO₂ particles. With increase of the concentration of vanadyl sulfate precursor, the amount of large particles increases significantly, and the particle size is more than 100 nm. The VO₂ particles obtained via pyrolysis of vanadyl dichloride are the secondary and primary particles. With increase of the pyrolysis temperature and precursor concentration, the dispersion of the particles increases obviously, and the number of small particles increases, and the particle size is about 100 nm.
