Hydrothermal Synthesis and Photocatalytic Property of CdLa<sub>2</sub>S<sub>4</sub> Hierarchical Microspheres

In this study, CdLa 2 S 4 hierarchical microspheres have been successfully synthesized through a hydrothermal method without any surfactants or templates. The crystal structure, morphology, and optical properties of the products were characterized by X-ray diffraction, scanning electron microscopy, and UV-vis diffuse reflectance spectroscopy. The results showed that the reaction time affects the structure and morphology of the CdLa 2 S 4 products. Finally, the CdLa 2 S 4 microspheres showed perfect photocatalytic properties for the degradation of the methyl orange solutions.
