## Description

- description: Photocatalytic removal of organic pollutants emerging from untreated
    industrial and aquaculture wastewater are still limited by catalytic efficiency
    and stability in practical application. In this study, we report the development
    of a silicone-immobilized, PEG-assisted Ag-doped TiO2 composite for efficient
    and sustainable removal of organic pollutants under solar irradiation. Firstly,
    a silicone-immobilized pristine TiO2 (S-TiO2) photocatalytic system was developed,
    demonstrating superior and stable removal of the organic pollutant Rhodamine B
    (Rh B) compared to PVA-TiO2 and dip-coated TiO2. Subsequently, pristine TiO2 was
    modified with the surfactant PEG, Ag species (Ag2O, Ag3PO4), and synthesized using
    the hydrothermal method, immobilized on silicone (S-H-PEG/PAgT). The S-H-PEG/PAgT,
    characterized by SEM, XRD, UV–Vis, and WCA revealed surface roughness, crystalline
    phase, excellent light absorption in the visible region, a narrow band gap, and
    hydrophobicity. The S-H-PEG/PAgT showed enhanced catalytic performance than S-TiO2
    (Control) in the removal of tetracycline, a representative emerging organic contaminant.
    Furthermore, it displayed remarkable stability over 10 cycles and practicability
    in environmental conditions. Mechanism analysis revealed •O2– and h+ as the dominant
    active species involved in the catalytic reaction. Notably, a synergistic effect
    of surface hydrophobicity, roughness, and photocatalytic activity contributed
    to the reduction of pollutants. Therefore, the developed novel solar light driven
    S-H-PEG/PAgT photocatalytic system shows great promise for practical purification
    of organics pollutants in wastewater.
