Porous organic polymers (POPs) have long been considered as prime candidates for carbon dioxide (CO2) capture, separation, and conversion. Especially their permanent porosity, structural tunability, stability relatively low cost are key factors in such considerations. Whereas heteratom-rich microporous networks well amine impregnation/functionalization actively exploited to boost the CO2 affinity of POPs, recently, focus has shifted engineering pore environment, resulting a new generation highly POPs rich heteroatoms featuring abundant catalytic sites capture conversion into value-added products. In this review, we aim provide insights structure-property relationships governing using highlight recent advances field.

Photo-Responsive Signatures in a Porous Organic Polymer Enable Visible Light-Driven CO₂ Photofixation

ACS Sustainable Chemistry & Engineering, Год журнала: 2023, Номер 11(6), С. 2066 - 2078

Porous organic polymers (POPs) continue to garner immense attention for CO2 capture and sequestration (CCS) as well fixation generate useful chemicals alleviating global warming. Functionally engineered, visible light responsive photopolymers with extended π-conjugation abundant heteroatoms enable photogenerated charge carriers, enhancement in absorption, higher separation, reduction recombination during photocatalysis. In this work, we have explored the construction of a chemically stable, pyridine-equipped, imine-linked porous polymer (Py-POP) by template-free Schiff base condensation 1,3,5-tris(4-aminophenyl) benzene (APB) 2,6-pyridinedicarboxaldehyde (PDC). This donor–acceptor Py-POP extensive π-conjugations enables photocatalytic styrene epoxide (STE) under illumination. We achieved an impressive conversion STE carbonate (STC) (∼99%) optimized reaction conditions using tert-butyl ammonium bromide (TBAB) promoter. Both efficient adsorption activation are enabled existence both imine pyridine moieties Py-POP. The interaction between is further illustrated density functional theory (DFT) calculations that show all POP-CO2 interactions favorable exergonic. Using situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) characterization techniques, elucidate mechanistic pathways active key surface species photofixation Our results provide insight into effectiveness efficient, sustainable photocatalysts light-driven various energy applications.

The research in advanced materials for effective CO2 capture and conversion is an imperative duty the next years. In this sense MOF are being intensively tested purpose. Herein, seven different copper-based with functional organic groups their linkers have been assessed to comprehend some structural features that influence transformation via cycloaddition reaction epoxides: Cu-URJC-1 (tetrazole group), Cu-URJC-8 (primary amine Cu-MOF-74 (hydroxyl JUC-62 (azo PCN-16 (triple bond HNUST-1 (amide group) HKUST-1. When epichlorohydrin was used as a substrate, produced best epoxide (90%) selectivity cyclic carbonate (>99%), despite showing modest surface area. This result can be explained by higher basicity of primary amines than other basic MOFs. However, when styrene oxide led results toward 60 86%, respectively. achieved because material presents synergic effect having its flexible structure 12 Å channels, favors diffusion, great number nitrogen atoms, which increase reactivity carbon dioxide. summary, presence atoms linker increases promoting molecule.
