Synthesis of Mo,W,and Mo- and W-doped multiwall VONTs via sol-gel and hydrothermal methods

Mo,w,and mo and w were doped into multiwall vanadium oxide nanotubes. the syntheses were performed using sol-gel method followed by hydrothermal method. the synthesized samples were characterized by xrd,sem,edx,and tem techniques. the xrd patterns of the synthesized samples indicated that mo and w could be doped into vonts totally up to 50. the sem and tem images showed that the prepared samples have tubular and multiwall morphology and open ends. © 2013 roya rouhani et al.
