Two-dimensional (2D) materials have attracted much attention in the past decade. They offer high specific surface area, as well as electronic structure and properties that differ from their bulk counterparts due to the low dimensionality. Graphene is the best known and the most studied 2D material, but metal oxides and hydroxides (including clays), transition metal carbides and nitrides (MXenes), dichalcogenides, boron nitrides (BN), carbon nitrides, monoelemental Xenes (including phosphorene and bismuthene), and other materials that are one or several atoms thick are receiving increasing attention. The specific chemical and physical properties of 2D materials can influence the electrochemical charging and discharging processes, which in turn affects the ability of the device to convert and store energy. 2D materials have been used in numerous applications and in different fields of research such as energy storage and conversion, electronics as well as biomedicine, biosensing, and chemical sensing, etc.
Considering the current strong interest of scientists in the physicochemical properties of 2D materials and the potential for electrochemical applications, as well as the challenges faced during practical applications, this research topic aims to bring together a wide range of recent original research articles, reviews, and prospective articles on 2D materials in the field of electrochemical batteries, supercapacitors, electrocatalysis. By focusing on the atomic structure, surface morphology, and physicochemical properties of 2D materials, it will reveal the general rules for the enhancement of their electrochemical performance.
This research topic will include (but not limited to) the following:
• The synthesis, characterization, and sensing abilities of 2D materials and composites.
• Surface engineering, interface engineering, and defect engineering of 2D materials towards boosting its electrochemical performance.
• Current challenges and prospects of 2D materials in electrochemical batteries, supercapacitors, electrocatalysis, etc.
