摘要
The MoO3 catalysts as a wet air oxidation catalyst have been synthesized by a simple hydrothermal method. During the synthetic process, a detailed orthogonal design on the preparation conditions was performed, aiming to optimize the parameters to produce MoO3 with the most prominent catalytic performance. The catalytic activities of the synthesized materials were evaluated via the decolorization of dye wastewater at room conditions. The effects of calcination temperature, catalyst dosage, and initial concentration of Rhodamine B (RhB) on the degradation efficiency were investigated, where it was found that the sample calcinated at 400 degrees C exhibited superior catalytic performance.
