Influence of Vanadium incorporated mesoporous silica on the decolorization of orange G under visible light irradiation

Abstract

Mesoporous MCM-41 material was synthesized and it was successfully incorporated with Vanadium at room temperature by simple co-precipitation method. Higher portion of V⁺⁵ was noticed in the framework of V-MCM-41 material without disturbing the mesoporosity. The materials were characterized by X-ray diffraction (XRD), Nitrogen adsorption-desorption studies (BET method, S_BET), scanning electron microscope coupled with electron dispersive x-ray spectroscopy (SEM-EDAX), and UV-Vis diffused reflectance (UV-Vis DRS) techniques. The catalytic activity of the synthesized materials were investigated toward the removal of orange G dye (OG) and was observed that the VMCM-41 has superior catalytic activity in the presence of hydrogen peroxide.
