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

Abstract The wastewater containing phenol is harmful, and the process complicated, photocatalytic oxidation technology believed to be greenest promising strategy for contaminants removal because of solar energy utilization no additional oxidants. Herein, manganese dioxide(MnO 2 ) doped with metal was fabricated by a low-temperature hydrothermal method, specific surface area MnO photocatalyst significantly enhanced doping ion. This making performance improved obviously, further applying degradation under visible light irradiation at room temperature.
