Synthesis of g-C3N4/TiO2 nanostructures for enhanced photocatalytic reduction of U(vi) in water

Yuelin Liu et al.

Summary: The Z-scheme g-C3N4/TiO2 catalysts were successfully synthesized through a thermal synthetic approach, showing excellent photocatalytic activity for U(vi) reduction under UV light irradiation. The photocatalytic tests demonstrated that g-C3N4/TiO2 exhibited significantly higher activity compared to the raw materials TiO2(P25) and g-C3N4, with 1.64 and 56.97 times enhancement, respectively.
