Abstract [en]

The influence of the hydrothermal conditions used for preparing precursors was studied with respect to the properties of the resulting KOH-activated carbons (KOH-ACs). The influence of the hydrothermal temperature (180 vs. 240 degrees C) was only minor on the textural properties of the KOH-ACs. However, the hydrothermal conditions did affect the electrical conductivity of the KOH-ACs. A higher conductivity was observed for the ACs prepared from precursors at the higher temperature and shorter reaction time. This study highlights an overlooked relationship in-between the degree of condensation in the precursors prepared from hydrothermal carbonization and the electrical conductivity of the corresponding ACs.
