Pillared graphene structures, from a practical viewpoint, are very interesting novel carbon materials. Combining the properties of graphene and nanotubes, such as durability, chemical purity and a controlled structure, they were proven to be effective membranes for noble gas separation processes. Here, we examine their possible use for other, more commercially useful gas mixture separation, i.e. air and coal gas. The mechanism of air gas transport through the pillar channels is studied, and the prospective application of 2-D pillared membranes in effusion-like processes provided. The separative abilities of hybrid systems consisting of membranes with different channel diameters in relation to coal gas are proven to be promising.
从实际应用的角度来看，柱状石墨烯结构是非常有趣的新型碳材料。它们兼具石墨烯和纳米管的特性，如耐久性、化学纯度和可控结构，已被证明是用于稀有气体分离过程的有效膜材料。在此，我们研究了它们在其他更具商业价值的气体混合物分离方面的潜在用途，即空气和煤气的分离。研究了空气通过柱状通道的传输机制，并探讨了二维柱状膜在类似渗流过程中的潜在应用。结果表明，由具有不同通道直径的膜组成的混合系统对煤气的分离能力很有前景。
