Visible-Light-Induced Photocatalytic Degradation of PAH-Contaminated Soil and Their Pathways by Fe-Doped TiO<inf>2</inf>Nanocatalyst

© 2018, Springer Nature Switzerland AG. The aim of the present study was to establish the photocatalytic efficiency of Fe-doped TiO2nanocatalysts toward polycyclic aromatic hydrocarbons (PAHs), which were phenanthrene, anthracene, and fluoranthene, contaminated soil under visible irradiation. The mo...
