摘要

本研究采用溶液燃烧合成法(SCS)合成了铝酸盐尖晶石型材料MAl2O4，研究了元素(M = Ca和Ba)对其结构，主要是结晶度和光学性能的影响。通过x射线衍射(XRD)、傅里叶变换红外光谱(FT-IR)和紫外可见漫反射光谱(UV-DRS)对其进行了表征。XRD和FT-IR分析结果表明，CaAl2O4和BaAl2O4形成了单相尖晶石结构。采用Tauc方法对CaAl2O4和BaAl2O4的带隙能进行了研究，得到的带隙能分别为3.93 eV和3.77 eV。结果与文献报道的数据吻合较好。

Structural and Optical Properties of MAl2O4 Spinel-type Prepared by Solution Combustion Synthesis Method for Photocatalytic Application

In this research, the aluminate spinel type materials, MAl2O4, are synthesised by solution combustion synthesis (SCS) method to investigate the effect of the element (M = Ca and Ba) on their structural, mainly crystallinity and optical properties. The characterisations are examined by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and UV-visible diffuse reflectance spectroscopy (UV-DRS). The XRD and FT-IR results showed the formation of the single-phase spinel structure of CaAl2O4 and BaAl2O4. The band gap energy was investigated using the Tauc method, and the obtained values were 3.93 eV and 3.77 eV for CaAl2O4 and BaAl2O4, respectively. The results showed a good agreement with the data as reported in the literature.
