Abstract
Abstract A multifaceted ternary MoS 2 /Al 2 O 3 /g-C 3 N 4 nanocomposite was prepared from a simple and facile hydrothermal method, which has good photocatalytic performance for the degradation of crystal violet (CV) dye under visible light irradiation. As a result of wide structural features for the charge separation mechanism, the formation of a ternary heterojunction affects the photocatalytic activity of the MoS 2 /Al 2 O 3 /g-C 3 N 4 nanocomposite remarkably. The photocatalytic activity of ternary nanocomposite was approximately 10.28 and 1.65 times higher than that of pure g-C 3 N 4 and 20Al-gCN, respectively. More significantly, the ternary nanocomposite also showed good photostability and reusability. The enhanced visible light photocatalytic activity was attributed to the effective photocatalytic mechanism of charge separation of the ternary system, whereas the surface properties were key factors for photodegradation of the CV dye.
