New Advances in 2D Materials for Catalysis

Recent advances in the field include the development of single atom catalysis using 2D materials. Here, individual metal atoms are dispersed on the 2D material substrate, which can offer highly efficient and selective catalysis due to the maximization of active sites.

The heterogenous nature of these systems, such as van der Waals heterostructures, opens up new avenues for catalysis, offering opportunities to engineer active sites at atomic scales. For example, they have been employed as electrocatalysts for oxygen reduction reactions, a crucial process in fuel cells and metal-air batteries.
