Abstract
The key to solving environmental and energy issues through photocatalytic technology requires highly efficient, stable and eco-friendly photocatalysts. Graphitic carbon nitride (g-C(3)N(4)) is one of the most promising candidates except for its limited photoactivity. In this work, a facile and scalable one-step method is developed to fabricate an efficient heterostructural g-C(3)N(4) photocatalyst in situ coupled with MoS(2). The strong coupling effect between the MoS(2) nanosheets and g-C(3)N(4) scaffold, numerous mesopores and enlarged specific surface area helped form an effective heterojunction. As such, the photocatalytic activity of the g-C(3)N(4)/MoS(2) is more than three times higher than that of the pure g-C(3)N(4) in the degradation of RhB under visible light irradiation. Improvement of g-C(3)N(4)/MoS(2) photocatalytic performance is mainly ascribed to the effective suppression of the recombination of charge carriers.
