摘要

This study reports a simple thiourea reduction method to prepare nanostructured Cd₄GeS₆ with direct band gap. Samples were characterized by X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), high resolution transmission electron microscopy (HRTEM), and UV-Vis diffuse reflectance spectra (UV-Vis). The photocatalytic activity of the Cd ₄GeS₆ was evaluated by the degradation of methylene blue (MB) aqueous under visible light irradiation. The enhanced activities of Cd ₄GeS₆ can be attributed to the direct band gap and large surface area, which is favorable for degradation of reactants, enhancement of photo-adsorption and transfer of photogenerated carriers.
