Fabrication Of Ternary Metal Sulfide Quantum Dots Loaded On Molecular Sieves As A Photocatalyst
The synthesis of ZnCdS nanomaterial in MCM-41 matrix has been realized by chemical synthesis between MCM-41, ZnCl2 and CdCl2 via an ion exchange method in aqueous solution. X-ray diffraction analysis (XRD), diffuse reflectance spectroscopy (DRS), transmission electron microscopy (TEM) and fourier transform infrared (FT-IR) were used to characterize the products. Several parameters were examined, catalyst amount (0.1-6 g L-1), pH (3-12) and initial concentration of MB (0.16-3.2 ppm). The extent of degradation was estimated from the residual concentration by spectrophotometrically. The average size of ZnCdCl2 in MCM-41 nanostructure was obtained about 3 nm by TEM.
