- Note:
- [a] The performance of mixed-matrix membrane was selected based on the most optimal performance in terms of O2 permeability and/or O2/N2 selectivity
- [b] The term “Pure” for the O2/N2 feed ratio refers to pure-component measurements. The selectivity is calculated based on pure-component O2 and N2 permeabilities
- [c] Based on optical micrograph
- [d] No information on the particle size
