The interface will control the morphology, leading to different chemical and physical properties. We obtained NaNbO3 with the morphology of triangular pyramids and cubes on the heterogeneous and homogeneous substrate by hydrothermal method, respectively. In comparison with the cube sample, the triangular pyramid one exhibits higher photocatalytic oxidization activities for 2,4-dichlorophene and rhodamine B degradation under full arc irradiation of Xe lamp. The (OH)-O-center dot radical coming from O-center dot(2)-with the intermediate of H2O2 is identified as the dominant oxide species via various control experiments. (C) 2016 Elsevier B.V.
