Preparation of the modified mesoporous beta materials and its application in wet catalytic degradation of methyl orange

摘要

The heterogeneous beta-supported transition metal catalysts were prepared by incipient wetness impregnation. The catalytic oxidation degradation of methyl orange was carried over the heterogeneous catalyst in the peroxide catalytic oxidation process. The pure beta materials showed quick adsorption equilibrium characterization, and the adsorption ratio was only 30%. Compared with the adsorption of the pure beta carrier, the Cu/beta and Fe/beta catalyst could effectively degrade methyl orange with high catalytic activity and easy catalyst separation from the solution using hydrogen peroxide as oxide. The methyl orange removal efficiency could reach 99% in the optimum experimental conditions. The optimal mental content for Cu, Ag, Mn, Fe and Co was 5%, 8%, 0.3%, 1% and 0.3%, respectively.
