In this study, we present the use of sucrose (CHO), which exists in abundance in nature, to prepare a carbon membrane without any preceding treatments. The preparation procedure was conducted using a low pyrolysis temperature, , in the range of 300-500 °C, followed by complete formation of the structure of the carbon membrane. The gas separation characteristics of the resulting membranes were assessed by evaluating both hydrogen and methane permeation. The highest selectivity obtained for H/CH was 31.34 with H permeability of 459.24 GPU. The entire fabrication procedure was designed to be economical in order to facilitate any future commercialization.
在本研究中，我们展示了使用自然界中大量存在的蔗糖（碳水化合物）来制备无需任何预处理的碳膜。制备过程采用低热解温度，在300 - 500°C范围内，随后碳膜结构完全形成。通过评估氢气和甲烷的渗透率来测定所得膜的气体分离特性。氢气对甲烷的最高选择性为31.34，氢气渗透率为459.24 GPU。整个制造过程设计得较为经济，以便于未来的商业化。
