Preparation, Characterization and Photocatalytic Properties of CdS and Cd_(1-x)Zn_xS nanostructures

摘要

Synthesis and photocatalytic properties of CdS and Cd_xZn_(1-x)S nanoparticles from thermal decomposition of metal complexes in presence of long chain amines are presented. Thermal decomposition can be achieved by conventional heating process. The prepared samples were characterized by powder x‐ray diffraction and UV‐Visible spectroscopy. The absorption response in the UV region has been applied for the photocatalytic degradation of Rhodamine‐B dye. The photocatalytic degradation reactions were performed on CdS and Cd_xZn_(1-x)S nanoparticles under UV light irradiation. Cd_xZn_(1-x)S nanoparticles show better photocatalytic degradation activity compared to CdS nanoparticles. Our studies prove that with the appropriate particle size, Cd_xZn_(1-x)S can efficiently decompose organic dyes under UV light irradiation with 415 nm.
