界面将控制形态，导致不同的化学和物理性质。采用水热法分别在非均质和均质衬底上制备出了三棱锥和立方体形貌的NaNbO 3。与立方体样品相比，三棱锥样品在紫外灯全弧照射下对2，4-二氯苯酚和罗丹明B的光催化氧化活性更高。通过各种对照实验，来自自由基dotO 2 −和中间体H2 O2的自由基dotOH被确定为主要的氧化物物种。
The interface will control the morphology, leading to different chemical and physical properties. We obtained NaNbO3with 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 radical dotOH radical coming from radical dotO2−with the intermediate of H2O2is identified as the dominant oxide species via various control experiments.
