摘要

Purification is a major bottleneck in generating low-cost commercial hydrogen. In this work, inexpensive high-performance H-2 separating membranes were fabricated by modifying the commercially successful interfacial polymerization production method for reverse osmosis membranes. Defect-free thin-film composite membranes were formed demonstrating unprecedented mixed-gas H-2/CO2 selectivity of approximate to 50 at 140 degrees C with a H-2 permeance of 350 GPU, surpassing the permeance/selectivity upper bound of all known polymer membranes by a wide margin. The combination of exceptional separation performance and low manufacturing cost makes them excellent candidates for cost-effective hydrogen purification from steam cracking and similar processes.
