Symposium NM02-2D Materials for Electrochemical Applications—Leading the Charge Through Thermodynamic and Kinetic Knowledge Gaps

2D materials have enormous potential as lightweight and flexible electrode materials for photoelectrocatalysis, energy storage, sensing, and the manipulation and storage of quantum information. Yet, several challenges prevent us from realizing these exciting applications, ranging from the inability to mass-produce 2D materials into electrochemical devices with high precision, to probing and elucidating their electronic excitations and energy relaxation mechanisms that lead to energy and charge transfer. Our symposium will highlight recent developments in 2D materials synthesis, characterization, theoretical treatment, and emerging applications. Topics will focus on current understanding of interfacial energetics and charge flow across the 2D material/electrolyte interface, which are central to the success of these emerging technologies. At graphene and TMD electrodes, the charged ions of the double layer act cumulatively as an effective electrostatic ‘gate’ that shifts the Fermi level relative to the band edges of the material via dynamic electron/hole doping. Additional effects of quantum capacitance on electrochemical reactions at 2D materials are not usually fully appreciated. We lack a concrete understanding of the best thermodynamic and dynamic description of the 2D material/electrolyte interface. Hence, this symposium aims to bring together a diverse group of materials scientists, synthetic chemists, electrochemists, theorists, and spectroscopists who are interested in addressing current knowledge gaps in the field of 2D electrochemistry.
