本文采用一种简单的绿色共沉淀法制备了纳米立方CaSnO 3。在该技术中，对于锡酸钙的制备，我们使用了由复杂结构的钙作为新的前驱体，并且在水作为绿色溶剂中进行了CaSnO 3的合成。络合前体的使用在反应介质中产生拥塞。研究了不同的合成条件，优化了沉淀剂（碱性）、pH值、温度、搅拌速度、表面活性剂以及表面活性剂的摩尔比等对产物形貌的影响，得到了质量和形貌均较好的产物。利用该CaSnO_3催化剂，在紫外光照射下，对酸性蓝92和酸性棕14两种偶氮染料进行了降解。结果表明，该粉体对染料（77%酸性棕14和67%酸性黑92）的降解具有良好的催化性能。因此，这些纳米立方体结构已被用作光催化剂在紫外光的存在下降解偶氮染料。(C)2016爱思唯尔B.V.保留所有权利。
In this work, nanocubes of CaSnO3 have been prepared by a simple and green co-precipitation method. In this technique, for preparation of calcium stannate, we have used from a complex structure of calcium as a new precursor and the synthesis of CaSnO3 have beers done in water as a green solvent. Using of complexing precursors were created a congestion in reaction medium. Different conditions have been studied in synthetic approaches and optimized the effect of different parameters on the morphology of product such as precipitation agent (alkaline), pH, temperature, the rate of stirrer, surfactants and the mole ratio of surfactants for preparation product and obtain the best product in terms of quality and morphology. By using of this CaSnO3, two types of azo dyes (acid blue 92 and acid brown 14) have been degraded at presence of ultraviolet light from aqueous solution. Results display that the powder shows appropriate catalytic behavior for degradation of dyes (77% acid brown 14 and 67% acid black 92). Therefore these nano-cube structures have been used as photocatalysts in presence of UV light for degradation of azo dyes. (C) 2016 Elsevier B.V. All rights reserved.
