Abstract

Abstract: A series of Znx Cd1-x S/C nanocomposites with different molar ratios of Zn/Cd were successfully synthesized through a facile solid phase thermal decomposition method. The structures and properties of these nanocomposites were characterized by X-ray diffraction (XRD), field emission scanning electron microscope (FESEM), X-ray photoelectron spectroscope (XPS), transmission electron microscopy (TEM), ultraviolet visible diffuse reflectance spectrum, electrochemical workstation and photocatalytic degradation test. The experimental results demonstrated that the photocurrent density of the Zn0.9 Cd0.1 S/C sample was the highest, which was 15 times that of the Zn0.1 Cd0.9 S/C sample. Among all the samples, Zn0.5 Cd0.5 S/C nanocomposite has the best photocatalytic activity. The degradation efficiencies of rhodamine B reached 98.4% under UV irradiation for 90 min. Carbon in Znx Cd1-x S/C nanocomposites improved the separation efficiency of photogenerated electrons and holes, enhancing the photocatalytic activity of Znx Cd1-x S/C nanocomposites.
