Anisotropy in photocatalytic oxidization activity of NaNbO3 photocatalyst

Author affiliations

Abstract

NaNbO3 single-crystal films with (100), (110) and (111) oriented crystal planes were grown on LaAlO3 (100), (110) and (111) substrates by pulsed laser deposition. The NaNbO3 films exhibit anisotropy in the photocatalytic oxidization activity for Rhodamine B (RhB) degradation. The increasing order of RhB degradation in Ar atmosphere under full arc irradiation of a Xe lamp is (100) < (110) < (111), which is consistent with that of ˙OH generation. The good linear relationship between the activity of RhB degradation and the coercive electric field indicates that the photocatalytic activity is closely related to the ferroelectric property.
