| Outline of Final Research Achievements |
In this research project, we have developed a novel co-production processes of mono-layer graphene and hydrogen via hydrothermal cathodic reduction under a subcritical water. In the developed process, the hydrothermal subcritical water solution was used to enhance the electrochemical reaction kinetics due to an increased electrolytic dissociation rate of the water and prevent the formation of undesirable amorphous carbon. The hydrothermal electrochemical reaction enabled low-temperature graphene growth on a Pt cathode surface with simultaneous hydrogen production. The conversion of hydrocarbons/basic chemicals to the high-value-added nanocarbons, including graphene, carbon nanotubes, and fullerenes, with valuable hydrogen has high potential economic/environmental benefits.
