Two-dimensional (2D) materials with diverse structural features are emerging as highly promising candidates for a range of energy applications. These include electrocatalysis for the oxygen reduction reaction (ORR), oxygen evolution reaction (OER), hydrogen evolution reaction (HER), and CO2 reduction reactions, as well as photocatalytic water splitting and CO2 reduction. Furthermore, 2D materials show significant potential in energy storage technologies, such as electrical double-layer capacitors (EDLCs), pseudocapacitors, and batteries. It is important to explore how synthesis parameters and surface modifications can be used to tune the conductivity, catalytic activity, and other performance-related properties of 2D materials.
The literature already provides various analyses of the activity parameters of leading 2D materials and their hybrids against traditional benchmark materials, offering an evolutionary perspective on performance advancements. For instance, doped graphenes achieve around 50% of their theoretical electrostatic maximum energy storage capacity in EDLCs. Notable early advances in pseudocapacitors have been achieved with graphene hybrids, layered double hydroxides, and metal oxide nanosheets. These innovations indicate promising prospects for similar electrode materials in batteries.
In the realm of lithium and sodium ion batteries, nanosheet hybrid structures have demonstrated enhanced electrode performance. Critical design criteria for nanosheet-based materials in energy conversion and storage include high electrical conductivity, robust porous nanosheet assemblies, and efficient ionic and molecular diffusion pathways. New research and developments are needed to overcome the challenges and seize the opportunities that lie ahead in this dynamic and rapidly evolving field.
This research topic aims to gather pioneering studies on the latest advancements in two-dimensional (2D) materials for energy conversion and storage applications. We welcome original research articles, reviews, and perspective papers that focus on novel synthesis methods, surface modifications, and the design of 2D materials to enhance their properties for various energy applications.
