Simple and facile synthesis W-doped VO2 (M) powder based on hydrothermal pathway

C Zhang, J Cheng, J Zhang, X Yang - International Journal of …, 2015 - Elsevier
The present study provides a simple and facile pathway to obtain undoped and W-doped VO
2 (M) powder by utilizing the inexpensive and low toxic NH 4 VO 3 precursor with an
economical and environmental friendly method. The XRD patterns exhibited that the W-
doped VO 2 powder was monoclinic phase, and W atom doping almost had no influence on
the crystal structure of VO 2 lattice. The grain size of W-doped VO 2 particles decreased as
W atom concentration increasing. SEM images showed that particles with 1~ 2 microns …
