Emerging Strategies for Nanoporous Membrane, Adsorbent, and Catalyst Synthesis

Most commercial nanoporous materials are based on zeolites, which have reached high technological maturity. With the paradigm shifts in energy, fuels, and chemicals production driven by urgent needs for decarbonization and sustainability, new membranes, adsorbents and catalysts will be needed for key roles in product purification, in feedstock fractionation, and for intensified chemical conversions and separations. In the last 20 years, research efforts on nanoporous materials like zeolites, metal organic frameworks (MOFs), and, more recently, covalent organic frameworks (COFs), graphenes/graphene oxides, and other 2D materials, provided demonstrations of breakthrough performance exceeding that of currently available technologies. Major synthesis concepts that allowed these developments (e.g., nanoparticle/nanosheet assembly, solvent-free crystallization, nanocomposites, epitaxial growth, post-synthesis modifications) will be highlighted. Fundamental gaps in nanoporous materials synthesis and separation and catalytic performance and how can they be addressed to enable new manufacturing paradigms will be discussed.
