## Description

- description: Nowadays, tetracycline (TC) contamination of surface water has become
    a comprehensive environmental problem that threatens the health and survival of
    animals and humans. It is essential to develop an efficient, and sustainable wastewater
    treatment strategy. This study introduces a novel Ag/Ag2O/BiPO4/Bi2WO6/g-C3N4
    (ABC) scheme photocatalyst for high-efficiency TC removal under visible light.
    Optimized g-C3N4 doping facilitated the electron transfer and provided more reaction
    sites for TC removal. It showed high efficiency, stable TC degra dation activity
    and environmental adaptability. Moreover, the active reaction site on TC was predicted
    via DFT calculation. In addition, through the analysis of the intermediates identified
    by LC-MS, the photo-decomposition pathways of TC were proposed. Based on the results
    of free radical trapping experiments and ESR spectroscopy, the mechanism of TC
    degradation was suggested. Finally, a toxicity assessment based on the molecular
    fractals data was carried out. The developed ABC showed higher visible light absorbance,
    better e-hþ separation, and higher phase purity and crystallinity. Overall, this
    study provides valuable insights into the development of scheme heterojunctions
    composite for efficient organic pollution degradation.
