| 摘 要： | 采用水热法制备了Sr2Ta2O7纳米片，并通过XRD、UV-Vis、SEM和TEM等手段对其进行了表征。以降解甲基橙溶液为反应模型，研究了Sr2Ta2O7纳米片的光催化性能。光催化结果表明，水热法制备的Sr2Ta2O7纳米片具有更高的光催化降解效率，为固相法制备的块体Sr2Ta2O7样品的2倍。二者催化性能上差异主要是由于两种方法制备的样品具有不同的晶粒大小和比表面积造成的。

| Abstract: | Sr2Ta2O7 nanosheets were prepared via a hydrothermal route and were characterized by XRD, UV-Vis absorption spectra, SEM and TEM. The photocatalytic activity of Sr2Ta2O7 nanosheets was investigated using the degradation of methyl orange as a model reaction. Photocatalytic results show that the Sr2Ta2O7 nanosheets exhibit higher degradation efficiency, 2 times higher than that of the bulk Sr2Ta2O7 sample. The different photocatalytic performances are mainly ascribed to the difference in the crystal size and surface area. |
