Abstract

In the present study, dichlorvos was degraded with photocatalytic active p-type semiconductor and n - type semiconductors. The nano - WO₃ was synthesized fromsodium tungstate andnano - TiO₂ was synthesized through sol-gel technique from titanium (IV) isopropoxide by hydrothermal treatment. The synthesized materials were characterized by different techniques such as XRD, FTIR, and SEM . In order to find out their photocatalytic ability and degradation of dichlorvos, experiment was carried out in aqueous suspension under UV light. The reaction pathway and mechanism were studied. From the evaluation, nano- TiO₂ showed higher activity when compare with other catalyst.
