Study of synthesis and photocatalytic performance of the monoclinic/cubic heterophase junction of rare earth doped zirconia

Eu and Y co-doped ZrO 2 is fabricated by solid state reaction method. ZrO 2 /Eu/Y products evolve from the monoclinic phase to the monoclinic/cubic phase in structure as the Eu ion content increases. Monoclinic/cubic heterophase junction is obtained during structural evolution, which develops a new route to fabricate ZrO 2 heterophase junction. Photocatalytic property measurement is carried out for ZrO 2 /Eu/Y materials. The ZrO 2 /Eu 0.1 /Y monoclinic/cubic heterophase junction promotes photogenerated electron-hole separation effectively and hence exhibits better photocatalytic performance.
