Abstract

Adsorption properties of gram-scale samples of different kind of arc discharge nanotubes were studied, namely: (A) raw collaret collected on the cathode, (B) raw soots collected on the lateral reactor wall, (C) thermally treated soot, and (D) thermally then chemically treated soot. The morphology, structure, and composition of these materials were characterized by SEM, TEM, TGA, and BET. In addition, hydrogen adsorption isotherms were recorded experimentally for A, B, and D samples over the pressure range of 0 to 55 bar at ambient temperature. Our experiments indicated a maximum-yet weak-hydrogen storage at room temperature of approximately 0.13 H2 wt% for the purified product (D).

摘要

研究了不同种类电弧放电纳米管克级样品的吸附特性，具体如下：(A) 收集在阴极上的未处理的领口状沉积物，(B) 收集在反应器侧壁上的未处理的烟灰，(C) 经过热处理的烟灰，以及 (D) 先经过热处理然后经过化学处理的烟灰。通过扫描电子显微镜（SEM）、透射电子显微镜（TEM）、热重分析（TGA）和比表面积分析（BET）对这些材料的形态、结构和组成进行了表征。此外，在环境温度下，对A、B和D样品在0至55巴的压力范围内实验记录了氢吸附等温线。我们的实验表明，纯化产物（D）在室温下的最大储氢量约为0.13 wt%，但储氢能力较弱。
