RESEARCH ON SYNTHESIS OF Ag@AgCl/MIL-101(Cr) PHOTOCATALYST FOR TREATMENT OF RY-145 DYE IN AQUEOUS ENVIRONMENT

Abstract

In this study, Ag@AgCl/MIL-101(Cr) photocatalyst material has been synthesized by the  two compounds, including support as metal-organic framework (MIL-101(Cr) and catalytic active phase as Ag@AgCl. MIL-101(Cr) synthesized by solvent thermal method. The synthesized Ag@AgCl/MIL-101(Cr) photocatalyst material characterized by the various physical-chemistry methods such as X-ray diffraction (XRD), fourier transform infrared (FT-IR), scanning electron microscopy (SEM), adsorption-desorption of N2 by BET and optical property off materials were determined by Ultraviolet–Visible Diffuse Reflectancee Spectroscopy (UV-Vis-DRS). The photocatalytic activity of Ag@AgCl/MIL-101(Cr) used to treat the RY-145 dye. The obtained results show that the treatment efficency reaches 91% in a perious of 4 h and without H2O2 and 96% with H2O2 as oxidizing agent. The treatment of RY-145 dye by Ag@AgCl/MIL-101(Cr) obeys speudo-second-order equation.
