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 tem-perature.Eventually,the KPC-based capacitive deionization(CDI)system showed excellent desalination perfor-mance,and the desalination capacity of KPC with an activation temperature of 800 ℃ was highest,reaching 51.33 mgNaCl 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.
