Biao Ji, Xudong Zheng, Zihuai Xu, Sifan Bao, Junwei Wang, Wenyu Weng, Jian Rong, Zhongyu Li IN: Journal of Cleaner Production, 435, 140501, https://doi.org/10.1016/j.jclepro.2023.140501

Herein, the authors developed amine-modified biochar-silica hybrid aerogels template cellulose nanocrystals (CNCs) for CO₂ capture. CNCs can self-assemble into an ordered lamellar structure and maintain their original structure after calcination in N₂ atmosphere. At the same time, we chemically modified the hybrid aerogels with amines. The ordered pore structure and chemical modification effectively enhanced the CO₂ adsorption capacity and rate of hybrid aerogels.
