Experimental study of manganese dioxide doped with metal for the treatment of phenolic wastewater

Abstract

The wastewater containing phenol is harmful, and the process is complicated, photocatalytic oxidation technology is believed to be the greenest and promising strategy for contaminants removal because of the solar energy utilization and no additional oxidants. Herein, manganese dioxide(MnO2) doped with metal was fabricated by a low-temperature hydrothermal method, the specific surface area of MnO2 photocatalyst was significantly enhanced by doping metal ion. This making the photocatalytic performance improved obviously, and further applying for phenol degradation under visible light irradiation at room temperature.

Manganese Oxide Hydrogel for Efficient Removal of Volatile Organic Compound in the Photothermal Water Purification

“…[ 40 ] In another literature, Qin et al prepared metal‐doped MnO 2 by a low‐temperature hydrothermal method to evaluate the photodegradation activity of MnO 2 on the phenol, and the results showed that the photocatalytic efficiency of pure MnO 2 toward phenol could reach 52%. [ 41 ] Apparently, MnO 2 ‐based materials have made remarkable achievements in photothermal evaporation and have also been proven in photocatalytic degradation of various organic contaminants.…”
