Outline of Final Research Achievements

To develop co-production system of hydrogen and valuable nanocarbon at low temperature, we studied the electrochemical synthesis of nanocarbon in sub-critical fluids. As a result, by hydrothermal cathodic reduction of acetic acid, mono-layer graphene and hydrogen co-production was achieved. This novel reaction system also facilitated the synthesis of more valuable nitrogen-doped graphene, and will contribute to the sustainable society as the innovative energy technology.
