Synthesis and spectroscopic studies of Fe۲O۳-xSx/S-doped gC۳N۴ nanocomposite materials

Herein, nanoporous Fe۲O۳-xSx/S-doped g-C۳N۴ (CNS) Z-scheme hybrid heterojuctions have beensuccessfully synthesized by one-pot in situ growth of the Fe۲O۳-xSx particles on the surface of CNS. Thecharacterization results show that S-doping in the g-C۳N۴ backbone can greatly enhance the charge mobilityand visible light harvesting capability. In addition, porous morphology of hybrid composite provides availableopen pores for guest molecules and also improves light absorbing property due to existence of multiplescattering effects. More importantly, the Fe۲O۳-xSx nanoparticles formed intimate heterojunction with CNSand developed the efficient charge transfer by extending interfacial interactions occurred at the interfaces ofboth components.
