Graphene oxide membranes supported on the ceramic hollow fibre for efficient H2 recovery
چکیده انگلیسی
The special channels and intrinsic defects within GO laminates make it a very potential candidate for gas separation in recent years. Herein, the gas separation performance of GO membranes prepared on the surface of ceramic α-Al2O3 hollow fibre was investigated systematically. The microstructures of ceramic hollow fibre supported GO membranes were optimized by adjusting operation conditions. And, the GO membrane fabricated at 30 min exhibited great promising H2 recovery ability from H2/CO2 mixture. At room temperature, the H2 permeance was over 1.00 × 10− 7 mol·m − 2·s− 1·Pa− 1 for both single gas and binary mixture. The corresponding ideal selectivity and mixture separation factor reached around 15 and 10, respectively. In addition, humility, operation temperature, H2 concentration in the feed and the reproducibility were also studied in this work.
