本文采用快速简单的共沉淀法合成了纳米锡酸钙。对于CaSnO 3的制备，使用氨作为沉淀剂。考察了阳离子、阴离子和中性表面活性剂对产物形貌的影响。通过改变Ca（Sal）2作为新的前驱体，获得了不同的形貌。配体作为具有空间位阻的封端剂导致制备具有较低粒径的产物。这些半导体纳米结构具有光催化活性，可以降解作为水污染物的有机染料。采用X射线衍射（XRD）、扫描电子显微镜（SEM）、傅里叶变换红外光谱（FT-IR）和紫外-可见光谱（UV-vis）等手段对合成材料进行了表征。
In this paper, calcium stannate nanoparticles were synthesized by a fast and simple co-precipitation procedure. For CaSnO3 preparation ammonia was used as precipitation agent. The effect of various surfactants such as cationic, anionic and neutral on the morphology of the products was investigated. By changing in Ca(Sal)2 as a new precursor different morphologies were obtained. Ligand as a capping agent with steric hindrance leads to preparation of product with lower particle size. These semiconductor nanostructures have photo-catalyst activities and can degrade organic dyes as water pollution. The synthesized materials were characterized by X-ray diffraction (XRD) technique, scanning electron microscopy (SEM) Fourier transform infrared (FT-IR) and UV-visible spectroscopy.
