A novel, three-dimensional (3D), self-supporting material-the crumpled graphene ball-was developed using an aerosol capillary approach. The resultant crumpled-graphene-ball architecture showed a self-supporting, 3D network microstructure with plenty of ridges and wrinkles. Due to their unique structural characteristics, the 3D balls exhibited a rapid adsorption rate and superior adsorption capacity toward the copper ion (Cu). It was noted that the adsorption capacity for Cu reached about 224.56 mg/g within 2 min. A high adsorption capacity, fast adsorption kinetics, excellent regeneration and reusability characteristics, and the ease of materials processing make these crumpled graphene balls ideal candidates for heavy metal ion decontamination in practical application.
采用气溶胶毛细法制备了一种新颖的三维（3D）自支撑材料——褶皱石墨烯球。所得褶皱石墨烯球结构具有自支撑的 3D 网络微结构，具有大量的脊和皱纹。由于其独特的结构特征，3D 球对铜离子（Cu）表现出快速的吸附速率和优异的吸附能力。值得注意的是，Cu 的吸附容量在 2 分钟内达到约 224.56mg/g。高吸附容量、快速吸附动力学、优异的再生和可重复使用特性以及易于处理材料，使这些褶皱石墨烯球成为实际应用中重金属离子净化的理想候选材料。
