Molecular Porous Photosystems Tailored for Long‐Term Photocatalytic CO2 Reduction

“…In particular, conjugated organic solids benefit from higher photochemical stability originating from additional molecular geometry constraints . Initiated by the seminal work of Antonietti and co‐workers using carbon nitride as both heterogeneous organic photosensitizer and catalyst for hydrogen evolution reaction published in 2009, conjugated polymer photocatalysts are attracting a growing interest . Key for their success is the tunability of the properties of the polymers by copolymerization of tailored monomers for a careful control of light absorption or porosity .…”

Recent Advances of Gas Transport Channels Constructed with Different Dimensional Nanomaterials in Mixed‐Matrix Membranes for CO2 Separation

“…The microporous polymer mainly includes PIMs, CMPs, PAFs, CTFs and PCs. Most of these microporous polymers own rigid and permanent porosities structure followed by chemical and thermal stability which make them more attractive in gas separation membranes . The common characterization of these microporous polymers can be shown that highly interconnected pores can be served as gas transport channels in membranes.…”

“…Although MMMs with 3D nanomaterials are very promising for CO 2 separation, there are real challenges that may restrict the future application. One important issue limiting some subclasses of microporous polymers (CTFs, HCPs, CMPs, and PAFs) in membrane application is the poor membrane formation due to the insolubility of these polymers . In addition, most of microporous polymers suffer physical aging and plasticization in CO 2 separation, especially for long‐running process .…”

Hierarchical Porous and Zinc‐Ion‐Crosslinked PIM‐1 Nanocomposite as a CO2 Cycloaddition Catalyst with High Efficiency

“…Microporous polymers usually possessh igh specific surface areas ascribed to the high microporosity, [16] which is ak ey requirementf or improving the density of catalytic sites. [17] Thus, microporous polymers are good candidates fort he fabrication of high-activity catalysts, including MOFs, [11a, 18] covalent organic frameworks (COFs), [19] polymers of intrinsic microporosity (PIMs), [20] hyper-crosslinked polymers (HCPs), [21] and conjugated microporous polymers (CMP).…”
