| 英文摘要 | Although ferroelectrics have potential applications in photocatalysis due to their highly efficient charge separation, their mechanism of charge separation is still unknown. A ferroelectric Sr0.7Ba0.3Nb2O6(SBN-70) semiconductor with a low ferro-paraelectric phase transition (65 degrees C) was studied. The photocatalytic activity for H-2 production by ferroelectric and paraelectric SBN-70 was examined. The spontaneous polarization in the ferroelectric phase strongly affected the photocatalytic performance and parallel ferroelectric domains significantly promoted photogenerated charge separation to result in better photocatalytic H-2 production. This knowledge provides an important basis for the fabrication of ferroelectric photocatalysts with improved charge separation ability.
