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.

摘要

合成了介孔MCM-41材料，并通过简单的共沉淀法在室温下成功地将其与钒结合。在 V-MCM-41 材料的框架中发现了较高的 V ⁺⁵部分，而不会干扰中孔。通过X射线衍射（XRD）、氮吸附-脱附研究（BET法，S _BET）、扫描电子显微镜结合电子色散X射线光谱仪（SEM-EDAX）和紫外-可见漫反射（ UV-Vis DRS) 技术。研究了合成材料对去除橙色 G 染料 (OG) 的催化活性，并观察到 ​​VMCM-41 在过氧化氢存在下具有优异的催化活性。
