- •
Catalysts were prepared by deposition of manganese and cerium oxides on Fe-MCM-41.
- •
The catalysts were significantly effective in catalytic ozonation of oxalic acid.
- •
Loading of cerium oxide was found to be more effective than manganese oxide alone.
- •
The highest degradation of organic carbons occurred at optimum catalyst loadings.
- •
The mechanism of oxidation involves the adsorption of oxalic acid on the surface.
