In this research, we used a fast and simple method for synthesis of calcium titanate (CaTiO₃) and calcium ferrite (CaFe₂O₄) nanostructures: microwave assisted co-precipitation method. The effect of time, microwave radiation power and type of solvent on the morphology of magnetic nanoparticles was studied. Calcium ferrite/calcium titanate (CaFe₂O₄/CaTiO₃) nanocomposite was prepared by the same method. The morphology and particles size of samples were studied by scanning electron microscopy. The porous nanostructure of CaTiO₃ and CaFe₂O₄/CaTiO₃ were ideal for photocatalytic behavior. The crystallographic properties of products were analyzed using X-ray diffraction technique. The purity of the samples confirmed by Fourier transform infrared spectroscopy. The magnetic property of CaFe₂O₄ and CaFe₂O₄/CaTiO₃ nanoparticles was determined by vibrating sample magnetometry. Both products had ferromagnetic properties with nanocomposite being a hard ferromagnetic sample. The photocatalytic behavior of CaTiO₃ and prepared nanocomposite was studied by measuring degradation efficiency of three different acidic dyes irradiated under UV–Visible light in different initial conditions. The results confirmed that both products have photocatalytic properties, but the CaFe₂O₄/CaTiO₃ has a higher photocatalytic activity due to coupling of two semiconductors, which can be employed for effective charge separation and increase of lifetime in the charge carriers.

在这项研究中，我们使用了一种快速简单的方法来合成钛酸钙 (CaTiO ₃ ) 和铁酸钙 (CaFe ₂ O ₄ ) 纳米结构：微波辅助共沉淀法。研究了时间、微波辐射功率和溶剂类型对磁性纳米粒子形貌的影响。用同样的方法制备铁酸钙/钛酸钙（CaFe ₂ O ₄ /CaTiO ₃）纳米复合材料。通过扫描电子显微镜研究样品的形貌和粒径。CaTiO ₃和CaFe ₂ O ₄ /CaTiO ₃的多孔纳米结构是光催化行为的理想选择。使用X射线衍射技术分析产物的晶体学特性。通过傅里叶变换红外光谱确认样品的纯度。CaFe ₂ O ₄和CaFe ₂ O ₄ /CaTiO ₃纳米颗粒的磁性能通过振动样品磁强计测定。两种产品都具有铁磁特性，纳米复合材料是一种硬铁磁样品。CaTiO ₃的光催化行为并通过测量三种不同酸性染料在不同初始条件下在紫外-可见光照射下的降解效率来研究制备的纳米复合材料。结果证实，两种产品都具有光催化性能，但CaFe ₂ O ₄ /CaTiO ₃由于两种半导体的耦合而具有更高的光催化活性，可用于有效电荷分离和增加电荷载流子的寿命。
