During the photodegradation process, the electrons from
the valance band of Zr/Ag-TiO2 can migrate easily to the
conduction band by absorbing visible light, leaving holes in
valence band Eq (2). These photogenerated electrons from the
conduction band scavenged by surrounding oxygen absorbed
on the surface of the product and convert them into

degradation pathway and possible intermediate compounds
during degradation were investigated by LC–MS analysis. In
order to evaluate the phytotoxicity of intermediate products
during photodegradation process two different seeds V.
radiata and P. vulgaris were utilized. The toxicity analysis
suggested that degraded metabolites showed less toxic nature
compared to normal EE2 and AB-52. We believe that the
present work furnishes the ability of multifunctional
nanomaterials to not only degrade the hazardous pollutants
but also detoxify them during photo catalysis.
