Tailored TiO2 layers for the photocatalytic ozonation of cumylphenol, a refractory pollutant exerting hormonal activity

Photocatalytic ozonation by Al-supported TiO2 films is successfully applied to the mineralization of 4-cumylphenol, a recalcitrant endocrine disrupting compound. A possible reaction mechanism implying the intermediate formation of bisphenols is proposed on the grounds of HPLC-MS and FTIR analyses.
