ABSTRACT
Efficient electrocatalytic materials are an essential part of any compact, efficient, fast, and high-performance devices, in biological sensing, batteries, supercapacitors, fuel cells, etc. Recently, exfoliated 2D nanomaterials are projected as a promising replacement of conventional materials for cost-effective, superior, and modular devices working on the principles of electrochemistry. Additionally, several of these atomic/nanolayered materials are efficient as noble metals in catalysts, thus they can reduce the production/installation cost tremendously. In many electrochemical applications of 2D materials, the edge atoms play a significant role in determining their activity. The electrochemical properties of several of these materials can be tailored by doping, intercalation, functionalization, hybridizing, heterolayer stacking, and forming composites. The 2D layered materials become an important class of materials with properties irreplaceable with other materials. This chapter highlights the recent developments of exfoliated 2D materials, such as graphene, transition metal dichalcogenides, MXenes, and layered hydroxides in electrochemical applications.
