Synthesis of the ZnGa 2 S 4 Nanocrystals and Their Visible‐Light Photocatalytic Degradation Property

Nanostructured ZnGa 2 S 4 with indirect band gap was prepared by a simple thiourea reduction method. As‐prepared samples were characterized by X‐ray diffraction (XRD), high resolution transmission electron microscopy (HRTEM), energy‐dispersive X‐ray spectroscopy (EDX), and UV‐Vis diffuse reflectance...

Description
Summary:Nanostructured ZnGa 2 S 4 with indirect band gap was prepared by a simple thiourea reduction method. As‐prepared samples were characterized by X‐ray diffraction (XRD), high resolution transmission electron microscopy (HRTEM), energy‐dispersive X‐ray spectroscopy (EDX), and UV‐Vis diffuse reflectance spectra (UV‐Vis). The visible‐light photocatalytic activity of the ZnGa 2 S 4 was evaluated by the degradation of methylene blue (MB) aqueous solution. The high photoactivities of ZnGa 2 S 4 can be attributed to the small band gap and large surface area, which is beneficial for degradation of pollutants and enhancement of transfer of photogenerated carriers.
