Fabrication of ternary GO/g-C3N4/MoS2 flower-like heterojunctions with enhanced photocatalytic activity for water remediation

Fabrication of ternary GO/g-C3N4/MoS2 flower-like heterojunctions with enhanced photocatalytic activity for water remediation
It is extremely important to design excellent nanojunction to improve photocatalytic performance. In this study, we use a simple method to construct GO/g-C3N4/MoS2 ternary-layered nanostructures as an effective photocatalyst for environmental purification using solar energy. The as-prepared materials have more adsorption sites and response sites due to the dual effects of NMP and CTAB. With the visible light irradiation, it has great photodegradation performance for MB, RhB and CV, as well as the photocatalytic reduction ability to Cr (VI). Meanwhile, the nanocomposites exhibit good reproducibility and stability during the cycle of the experiment. The designed heterostructures have a flower structure, which effectively improves the collection of electrons in MoS2 and holes in g-C3N4, effectively reducing the binding of photogenerated electron carriers. Furthermore, GO acts as a fast transport holes, which is attributed to superior its electrical conductivity. This work provides a new field of view for establishing high-efficient and easy-made photocatalysts with environmental remediation.
