本文报道了一种钛酸锶花状分级纳米结构.实验结果表明该钛酸锶花状分级纳米结构沿钛酸锶晶体的?111?方向生长,形成八个分支结构,每个分支结构由一系列纳米片堆叠而成,整个粒子具有花状的形貌结构.通过调节反应体系的p H,可以得到纳米立方、纳米球等其他形貌结构的钛酸锶晶体.所合成钛酸锶对光催化降解罗丹明B染料具有较高活性,其中花状分级纳米结构钛酸锶的光催化活性显著高于其他两种结构,在光催化领域具有潜在应用前景.
In this paper, a strontium titanate flower-like hierarchical nanostructure was reported. The experimental results show that the strontium titanate flower-like hierarchical nanostructures grow along the 111 direction of strontium titanate crystals and form eight branch structures, each of which has a Series of nanosheets stacked, the entire particle has a flower-like topography structure by adjusting the reaction system p H, can be nano-cubic, nanosphere and other morphological structure of strontium titanate crystals synthesized strontium titanate light Photocatalytic degradation of rhodamine B dye has high activity, of which the flower-like graded nanostructured strontium titanate photocatalytic activity was significantly higher than the other two structures in the photocatalytic potential has potential applications.
