中文摘要：

Cubic-perovskite (SrTiO ₃) 有一个大潜力在大量应用被利用。然而，当前，很，很少在他们的物理化学的性质上对形状和 SrTiO ₃ 的方面效果被知道。这大部分由于在在合成期间控制方面的形态学的困难。此处，我们为 singlecrystalline SrTiO ₃ 的控制方面、控制尺寸的制造描述一条灵巧的线路三角形的棱柱与高度暴露了 { 101 } 方面脸并且 { 111 } 结束脸。他们的 photocatalytic 表演的理论、试验性的研究证明了三角形的棱柱比 nanocubes 展出优异 photocatalytic 活动与暴露( 001 )为器官的沾染物的降级面对，它可以首先被归因于高得多的表面精力{ 101 }方面( 2.97 J/m ₂)并且{ 111 }方面( 2.80 J/m ₂)比的{ 001 }方面( 0.98 J/m ₂)。

英文摘要：

Cubic-perovskite （SrTiO3） has a great potential to be utilized in a wide range of applications. However, currently very little is known about the shape and facet effects of SrTiO3 on their physicochemical properties. This is largely owing to the difficulties in controlling the morphology of facets during synthesis. Herein, we describe a facile route for the facet- and size-controlled fabrication of single- crystalline SrTiO3 triangular prisms with highly exposed {101} side faces and {111} end faces. Theoretical and experimental studies of their photocatalytic performance have shown that triangular prisms exhibit superior photocatalytic activities than nanocubes with exposed （001） faces for the degradation of organic contaminants, which may be primarily attributed to the much higher surface energy of {101} facets （2.97 J/m^2） and {111} facets （2.80 J/m^2） than of that of {001} facets （0.98 J/m^2）.
