Abstract

Metal-organic framework (MOF)-derived carbon materials exhibit large surface areas, but dominant micropore characteristics and uncontrollable dimensions. Herein, we propose a self-sacrificial template-directed synthesis method to engineer the porous structure and dimensions of MOF-derived carbon materials. A porous zinc oxide (ZnO) nanosheet solid is selected as the self-sacrificial template and two-dimensional (2D) nanostructure-directing agent to prepare 2D ZIF-8-derived carbon nanosheets (ZCNs). The as-prepared ZCN materials exhibit a large surface area with hierarchical porosity. These intriguing features render ZCN materials advanced electrode materials for electrochemical energy-storage devices, demonstrating large ion-accessible surface area and high ion-/electron-transport rates. This self-sacrificial template-directed synthesis method offers new avenues for rational engineering of the porous structure and dimensions of MOF-derived porous carbon materials, thus exploiting their full potential for electrochemical energy-storage devices. On the surface: A self-sacrificial template-directed synthesis method is proposed to engineer the porosity and dimensions of MOF-derived carbon materials. By using a porous nanosheet solid as the self-sacrificial template and two-dimensional (2D) nanostructure-directing agent, 2D ZIF-8-derived carbon nanosheets are prepared, which exhibit a large ion-accessible surface area and rapid ion transport as the electrode materials for electrochemical energy-storage devices.
