Nanostructured porous carbon materials are technologically important for a variety of applications including the use as catalysts, electronic materials and energy storage devices. In this study, we fabricated multimodal porous carbons from cellulose by using easy, cheap and eco-friendly process with NaOH/Urea/Water solvent. In a certain concentration, a cellulose-NaOH-water complex encaged in the channel-like inclusion complex hosted by urea hydrates was carbonized as a interconnected multimodal porous carbon (IMPC). Therefore, unlike the template methods with tedious or complex procedure, we could obtain IMPCs by using very simple method that is composed of freeze-drying and carbonization of cellulose solution prepared by using NaOH/urea/water solvent. Because the novel carbons have high surface area as well as 3D interconnected multimodal porous structure, they have many possibilities with a variety of applications. Especially, we applied the IMPCs to catalyst supports for PEMFC. |
