A Critical Review on New and Efficient 2D Materials for Catalysis

The unique structure and properties of graphene make it have excellent performance in the field of catalysis. It can be modified in various ways to improve its catalytic ability. Notably, other 2D materials with similar properties to graphene (black phosphorus (BP), 2D transition metal dichalcogenides represented by molybdenum disulfide (MoS2) and tungsten disulfide (WS2), boron nitride (BN), and transition metal carbide and nitride (MXenes) and their hybrid materials also have a wide range of applications in the field of catalysis. In general, 2D materials can be used as catalysts, catalytic supports or electron donors. Therefore, they have been widely used in many catalytic reactions in recent years, such as photocatalysis, thermocatalysis, and electrocatalysis. In this paper, the research progress of the above 2D materials in the catalytic degradation of organic matter in water and carbon dioxide reduction reaction (CO2RR) is summarized. In addition, some excellent composite 2D catalysts in the fields of photocatalysis and electrocatalysis are summarized and compared. Finally, the opportunities and challenges of the above 2D materials in the field of catalysis are pointed out, and the development prospects of the 2D materials in the field of catalysis are addressed.
