Abstract
The key to solving environmental and energy issues through photocatalytic technology requires highly efficient, stable and eco-friendly photocatalysts. Graphitic carbon nitride (g-C3N4) 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-C3N4 photocatalyst in situ coupled with MoS2. The strong coupling effect between the MoS2 nanosheets and g-C3N4 scaffold, numerous mesopores and enlarged specific surface area helped form an effective heterojunction. As such, the photocatalytic activity of the g-C3N4/MoS2 is more than three times higher than that of the pure g-C3N4 in the degradation of RhB under visible light irradiation. Improvement of g-C3N4/MoS2 photocatalytic performance is mainly ascribed to the effective suppression of the recombination of charge carriers.

Summary
Energy issues and environmental pollution are among the most serious challenges for humans in the twenty-first century. In addition to the above-mentioned methods, a more efficient solution is to construct a semiconductor–semiconductor heterojunction to enhance the separation efficiency of photo-generated carriers [36,37,38]. Among these candidate counterparts, MoS2 has been attracting tremendous attention owing to its two-dimensional semiconducting properties because a two-dimensional/two-dimensional heterojunction can endow a higher charge mobility. A facile and scalable one-step synthesis method is proposed to develop g-C3N4/MoS2 hybrid photocatalysts. This one-pot preparation route is very easy and eco-friendly, avoiding harmful reactants. A better contact interface and strong Mo−N coupling effect formed between g-C3N4 and MoS2 efficiently improves the charge separation, resulting in a highly improved photocatalytic performance
