Abstract EN
Mo0.5W0.5O3 nanoparticles were prepared through the Pechini process and were characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM), FT-IR spectrometer, and differential thermal analysis (TG-DSC) analyses.
The polyesterification reaction, as the starting step, has a profound influence on the dispersion of the resulting nanoparticles.
The molar ratios CA : TM = 2 and EG : CA = 1.5 are favorable for the preparation of Mo0.5W0.5O3 nanoparticles having average particles size ranging from 2 to 9 nm.
Meanwhile, the molar ratios CA : TM = 4 and EG : CA = 0.19 are favorable for the preparation of Mo0.5W0.5O3 nanoparticles having an average particles size ranging from 11 to 29 nm.
For the calcination step, increased calcination time (eight hours) at 500°C is advantageous for allowing the monometallic phases enough time to transform into the desired bimetallic Mo0.5W0.5O3 phase.
