▎ 摘  要

Ultra-performance non-compact Graphene/Carbon Hollow Fibers/Graphene similar to(G/CHF/G) junction like membrane was successfully fabricated by chemical vapor deposition (CVD) of graphene on the two sides of carbon fibers pellet of with thickness of 6 mm. Mono-, bi-junction and tri-units junction membranes were loaded in column with specific parameters suitable for junction size. The column was made from special glass with controlled in/outlet stopper. The adsorption capacities of Mono-, bi-junction and tri-units junction like membranes were measured from adsorption isotherm at 25 degrees C and found to be 76, 93 and 117 mmol. CO2/gm G/CHF/G respectively. These promising results are attributable to G/CHF/G junction like membrane has ultra-high surface area coupled with mesoporous structure. Furthermore compactness of graphene layers with thickness average 67.5 angstrom on the surface of carbon hollow fibers act as true membrane reinforced by adsorption on cavities of carbon hollow fibers.
