| Outline of Final Research Achievements |
This research investigates the template-free production of porous carbonaceous materials by using sugar amphiphiles and hydrothermal procedure. The current templating-based protocols somewhat limit the opportunity of finely tuning nanostructural paramters such as pore size, shape or morphology. For the purpose of simplifying the porous carbon synthesis and of extending the degree of nanostructural controllability, this research focuses on chemical modification of sugars, endowing the precursors with an amphiphilic molecular property. This has allowed for direct and controlled nanostructuring during hydrothermal carbonization and, consequently, template-free production of porous carbonaceous nanostructures. The formed nanoscale pore system has further been demonstrated to be uniform and ordered, showing in an optimized system, the development of a bimodal-like pore system.
