Summary: | Effects of zirconium (Zr) doping into BiVO
powder on its structural properties and photocatalytic activity for O
evolution were examined. The formation of BiVO
powder crystallized in a monoclinic scheelite structure (
-BiVO
) was achieved when the sample was doped with a relatively small amount of Zr. The photocatalytic activity of Zr-doped
-BiVO
powder was much higher than that of non-doped
-BiVO
. However, further doping caused a reduction of photocatalytic activity for O
evolution due to the occurrence of structural alterations into tetragonal scheelite and tetragonal zircon structures. Similar effects of Zr doping were also observed for the photoelectrochemical (PEC) system based on BiVO
thin films doped with various amounts of Zr. Thus, Zr doping was confirmed to be effective for improvements of photocatalytic and PEC functions of BiVO
for water oxidation. |
