Fig 8

Visible light photocatalytic degradation of BTEX in aqueous medium in the presence of ZnO nanorods as supported photocatalyst. Upon photo excitation, BTEX molecules are photocatalytically degraded by the ZnO nanorods resulting in various types of intermediate byproduct, which upon successive photo-oxidation produces CO2, H2O and mineral acids leading to the complete mineralization of BTEX.
