As a novel two-dimensional carbon material, graphdiyne (GDY) is well-known for its unique pore structure and electronic structure. It has great potential in energy, catalysis and many other fields. In recent years, we have been committed to the design of new GDY based catalysts, aiming to thoroughly study their intrinsic characteristics and explore their applications in the environmental field, so that we could provide new research ideas for the development of catalysts.
