Summary: This study presents a strategy for the improvement of commercial supercapacitors by synthesizing mesopore-adjustable hierarchically porous carbon nanosheets. The results show that excessive improvement in surface area observed in gaseous atmospheres has little effect on the final performance due to blocked pore alleys. The fabricated carbon nanosheets with adjustable mesopores exhibit superior electrochemical performance compared to carbon-based supercapacitors with aqueous electrolytes in recent literature.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.
