(212a) Nanoporous 3D Graphene-like Carbons for Electrochemical Energy Storage

In this presentation, we showcase recent advancements in energy storage applications utilizing zeolite-templated carbon (ZTC) materials [1]. The ZTC synthesis involves metal-ion-catalyzed carbonization followed by the removal of zeolite templates [2]. Successful synthesis yields ZTC products characterized by well-ordered microporous structures boasting high surface areas (> 2500 m²g^-1) and remarkably narrow pore size distributions, typically around 1 nm [1]. This unique structure finds interesting application in various energy storage systems, including supercapacitors, lithium-ion batteries and capacitors [2–5]. Moreover, the nanopores of ZTC can accommodate guest species such as Co nanoparticles, molecular I₂, and MnO_x nanostructures, encapsulating them for prolonged cycling stability [6–8]. As reported in the literature, ZTC serves as an intriguing electrode material extending beyond traditional gas storage applications.
