Kelp-derived porous carbon for capacitive deionization: Trade-off effect of activation temperature
In this paper, a series of kelp-derived porous carbon (KPC) materials were prepared from kelp by using a pyrolysis-activation method, where KOH with a fixed ratio was applied as the activator under varying activation temperature. Eventually, the KPC-based capacitive deionization (CDI) system showed excellent desalination performance, and the desalination capacity of KPC with an activation temperature of 800 °C was highest, reaching 51.33 mg NaCl g −1 at 1.2 V. This work implies the trade-off effect of the activation temperature for the preparation and application of biomass-derived carbon materials, and provides some insights for carbon-based CDI materials.
