摘要/Abstract

摘要： 本文以稻壳为碳源，以离子液体1-丁基-3-甲基咪唑六氟磷酸盐(BMIMPF₆)为模板和辅助活化剂制备了多孔炭材料（PCs）. 多孔炭的比表面积达1438 m²·g^-1，总孔容达0.75 cm³·g^-1. 以PCs为超级电容器电极材料，6 mol·L^-1的KOH溶液为电解液组装成扣式电池，在0.05 A·g^-1的电流密度下，比电容高达256 F·g^-1；当电流密度增大至10 A·g^-1，其比电容仍保持在211 F·g^-1，展现出好的倍率性能. 所得的多孔炭电极均表现出优异的循环稳定性. 这一工作以BMIMPF₆作为模板和辅助活化剂，为合成生物质基超级电容器用多孔炭提供了一种新方法.

Abstract: It is still a challenge to prepare carbon materials with high specific surface area at low cost from renewable resources. Herein, the authors report an efficient approach to synthesize porous carbons (PCs) from rice husk with ionic liquid (1-butyl-3-methylimidazolium hexafluorophosphate (BMIMPF₆)) as a template and an activation agent. The as-made PCs featured the high specific surface area up to 1438 m²·g^-1. As electrodes for supercapacitors, PCs showed a high specific capacitance of 256 F·g^-1 at 0.05 A·g^-1 in 6 mol·L^-1 KOH aqueous electrolyte and a good rate performance of 211 F·g^-1 at 10 A·g-1. All the PC electrodes exhibited good cycle stability. This work provides a new way for efficient synthesis of PCs from biomass using BMIMPF₆ as a template and an assisted activation agent for high-performance supercapacitors.

Key words: porous carbon, BMIMPF₆, rice husk, supercapacitor
