“…The design of the ternary composite catalyst provides a bright idea for the construction of layered heterojunction catalysts. Vo et al 43 successfully prepared S-scheme SnS 2 /g-C 3 N 4 composite. Under visible light irradiation, its photodegradation performance of RhB is better than that of pure SnS 2 and g-C 3 N 4 , and the highest removal rate is 92.22% after 6 hours of irradiation.…”

Photocatalytic degradation of organic pollutants is considered an ideal method to solve the global environmental pollution problem. In this method, photocatalytic materials are regarded as the key factor. As an n‐type photocatalytic material, graphitic carbon nitride (g‐C3N4) has attracted much attention due to its suitable bandgap, nontoxicity, and high photostability. However, g‐C3N4 still has defects such as insufficient visible light absorption, low specific surface area, and easy recombination of photogenerated electron–hole pairs, which lead to the poor photocatalytic performance of g‐C3N4. Herein, to solve the above problems, thiourea, lemon juice, and tin chloride pentahydrate are used as precursors, while carbon quantum dots (CQDs) are used as electron mediators, and the third phase SnS2 is introduced by a hydrothermal and ultrasonic composite method. SnS2/CQDs/g‐C3N4 composites with Z‐type heterojunction are successfully prepared. The results show that the SnS2/CQDs/g‐C3N4 has a 2D0D2D structure, which effectively inhibits the recombination of photogenerated electron–hole pairs, making the material have better photocatalytic degradation activity for Rhodamine B (RhB). When the mass ratio of SnS2 is 15%, the photocatalytic degradation efficiency of RhB by the composite reaches the best, which is 87.8%. After four cycles, the photocatalytic degradation efficiency of the 15% SnS2/CQDs/g‐C3N4 composite still remains at 82.9%.

Abstract2D materials with their fascinating physiochemical, structural, and electronic properties have attracted researchers and have been used for a variety of applications such as electrocatalysis, photocatalysis, energy storage, magnetoresistance, and sensing. In recent times, 2D materials have gained great momentum in the spectrum of photocatalytic applications such as pollutant degradation, water splitting, CO2 reduction, NH3 production, microbial disinfection, and heavy metal reduction, thanks to their superior properties including visible light responsive band gap, improved charge separation and electron mobility, suppressed charge recombination and high surface reactive sites, and thus enhance the photocatalytic properties rationally as compared to 3D and other low‐dimensional materials. In this context, this review spot‐lights the family of various 2D materials, their properties and their 2D structure‐induced photocatalytic mechanisms while giving an overview on their synthesis methods along with a detailed discussion on their diverse photocatalytic applications. Furthermore, the challenges and the future opportunities are also presented related to the future developments and advancements of 2D materials for the large‐scale real‐time photocatalytic applications.
