In this study, MoS2/g-C3N4 nanocomposites were prepared and showed efficient uranium ions removal. The optimal composites containing 3% MoS2 demonstrated superior photocatalytic performance in reducing U(VI) due to the pivotal role of MoS2 in light adsorption and charge separation.
In this study, MoS2/g-C3N4 nanocomposites was prepared via an ultrasonication and calcination method and used for uranium ions removal from uranium containing solution. The optimum MoS2/g-C3N4 composites photocatalyst with the molar content of 3% MoS2 had the highest photocatalytic performance (93% reduction efficiency within 60 min irradiation time), which was approximately five times faster than that of pure g-C3N4. MoS2 plays pivotal roles in light adsorption, transfer and charge separation in photoreduction of U(VI) process.
