摘要

本文以海带为原料，采用热解-活化法制备了一系列海带衍生多孔碳（KPC）材料，在不同的活化温度下使用固定比例的KOH作为活化剂。最终，基于 KPC 的电容式去离子（CDI）系统显示出优异的脱盐性能，其中活化温度为 800 ℃ 的 KPC 脱盐能力最高，在 1.2 V 时达到 51.33 mgNaCl g-1。这项研究揭示了活化温度对生物质衍生碳材料制备和应用的权衡效应，并为碳基 CDI 材料提供了一些启示。

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.
