Abstract

Cerium oxide (Ce–O) and a novel cerium oxide-activated carbon composite (AC0–Ce–O) were tested in the ozonation of three selected aromatic compounds: benzenesulfonic acid, sulfanilic acid and aniline. The catalysts performance was compared to that obtained with the commercial activated carbon. All the tested materials enhanced the mineralization of the selected compounds. Generally, best results were achieved with the AC0–Ce–O composite.
