Abstract

Ozone initiated oxidation of 2-chloro,4-bromophenol, (CBP) in aqueous system catalyzed by 1, 2.5 and 5% loadings of 1:1 molar ratio of Ce-Zr oxide on TiO2 were studied. The synthesized catalysts were characterized via BET, ICP, PXRD, TPD, TEM, SEM, and FT-IR analysis. The powder XRD data revealed that Ce-Zr exists in three different phases on titania. SEM and SEM-EDX confirmed well dispersed metal oxides on titania surface. 1H NMR, IR and GC-MS positively confirm hydroxyfumaric acid (HFA) and oxalic acid (OA) as reaction products. 5% Ce-Zr/TiO2 showed best performance with100 % conversion in 4 h.
