Abstract: The use of membrane technology has developed rapidly since the proposal of the Robeson
upper bound. Nevertheless, the researchers proposed various methods and techniques to enhance the
permeability and selectivity to achieve a breakthrough of the upper bound. Metal-organic framework
(MOF) and covalent organic framework (COF) were the recently-interest- arising materials enhancing
gas separation performance. In this study, recent advances in MOF and COF were comprehensively
discussed in terms of the materials, properties and synthesis method. Later, the MOF and COF nanocomposite
mixed matrix membrane development was discussed to evaluate the recent improvement of
these membranes used in the O2/N2 gas separation performance. This work intends to overview the recent
progress and development of the metal-organic framework, covalent organic frameworks and the
used nanocomposite membrane in O2/N2 gas separation. This topic review was carried out from a
thorough literature review of metal-organic frameworks, covalent organic frameworks and the used
nanocomposite membrane in O2/N2 gas separation. Additionally, the recent achievement of the O2/N2
gas separation by nanocomposite membrane in term of permeability and selectivity are also discussed.
Findings from this study suggested that MOF and COF-based nanocomposite membranes could be
used in either the O2/N2 and N2/O2 gas separation process with the possibility of being involved in the
gas production sector.
