A TiO2 surface modified with copper(II) phthalocyanine-tetrasulfonic acid tetrasodium salt as a catalyst during photoinduced dichlorvos mineralization by visible solar light

- Visible solar light and CuPc-TiO2 as catalyst effectively mineralize insecticide Dichlorvos.
- A rate vs. [DDVP] bell shape profile supports O2 participation via sensitization.
- No intermediates are accumulated during treatment.
- CuPC-TiO2 is further activated as catalyst when solar UV light irradiation is included.
