Enhanced Photocatalytic Fuel Denitrification over TiO₂/α-Fe₂O₃ Nanocomposites under Visible Light Irradiation.

ABSTRACT: With increasingly stringent environmental regulations, the removal of nitrogen-containing compounds (NCCs) from gasoline fuel has become a more and more important research subject. In this work, we have successfully synthesized TiO₂/α-Fe₂O₃ heterogeneous photocatalysts with different mass ratios of TiO₂ vs. α-Fe₂O₃. Taking photocatalytic denitrification of typical alkali NCCs, pyridine, in gasoline fuel under visible light irradiation (λ ≥ 420 nm) as the model reaction, the TiO₂/α-Fe₂O₃ hybrids have exhibited enhanced photocatalytic activity compared with pure TiO₂ and α-Fe₂O₃, giving a pyridine removal ratio of ∼100% after irradiation for 240 min.
