Abstract

This study presents effective methods for utilizing the TiO₂ photocatalyst in environmental remediation, with a particular focus on the removal of the carbofuran pesticide (CBFP) from wastewater. Silver (Ag) was selected as a potential dopant to improve the optical properties as well as the electron-hole pair separation efficiency of TiO₂. Ag-doped TiO₂ (Ag-TiO₂) effectively decomposed 92.8% CBFP under solar light, which was significantly higher than that of TiO₂ (21.3%). Ag-TiO₂ also exhibited good reusability for CBFP degradation, with a reduction in removal efficiency of less than 3% after three cycles. In practical applications, Ag-TiO₂ successfully degraded 89.3% of CBFP in wastewater and 98.7% in surface water. The findings of this work bring an effective method for removing pesticide pollutants using Ag-TiO₂ photocatalyst.
