Carbonate-based hyper-cross-linked polymers with pendant versatile electron-withdrawing functional groups for CO₂adsorption and separation

Abstract

Simple and highly efficient preparation of porous hyper-cross-linked polymers (HCPs) with high surface area and manifold functionalities for high-performance CO2 uptake and selective separation has drawn multitudinous attention over the...

Green synthesis of hypercrosslinked polymers for CO2 capture and conversion: recent advances, opportunities, and challenges

“…3.2.2 CO 2 /CH 4 selectivity. Hou et al 48 designed a strategy to knit together carbonate-based HCPs. The hydroxyl groups in the carbonates, for which a hydrogen atom is partially or completely substituted by an alkyl group, are Lewis basic sites in the polymer and can enhance the specific interaction with CO 2 .…”

“…45 In recent years, porous organic polymers (POPs) have emerged as excellent adsorption and conversion materials. [46][47][48] Not only do they integrate the advantages of the above materials, but they are also expected to solve their disadvantages. The synthesis of POPs is usually carried out with special conditions, complex monomers for the covalent organic frame-works (COFs), [49][50][51] noble metal catalysts for conjugated microporous polymers (CMPs), 52,53 and an inert atmosphere for porous aromatic frameworks (PAFs) and polymers of intrinsic microporosity (PIMs), 54,55 all of which limit their industrial applications.…”

Phenanthrene Derived Nanoporous Hypercrosslinked Polymeric Adsorbent for CO2 Capture from Flue Gas and Removal of Organic Dyes from Wastewater

“…In this direction, Zhou et al have synthesized a series of HCPs of intrinsic microporosity (PIM), which display a CO 2 capture capacity of 6.7 mmol g −1 and a CO 2 HCP/N 2 selectivity of 26.5 at 298 K. 30 Hou et al reported a CO 2 capture capacity and a CO 2 /N 2 selectivity of 3.3 mmol g −1 and 20.1, respectively, at 273 K using a carbonate-based HCP as the adsorbent. 31 Begni and co-workers provided evidence regarding the function of PIMs in mitigating the aging effects of PIM-based mixed matrix membranes. 32 Moreover, because of the presence of extensive π electrons, the HCPs are believed to adsorb aromatic organic molecules like organic dyes by π−π interaction.…”

Combining Interpretable Machine Learning and Molecular Simulation to Advance the Discovery of COF-Based Membranes for Acid Gas Separation

“…8 Over the past two decades, nanoporous materials (NPMs) have become key materials for enhancing membrane separation performance. Zeolites, 9 metal−organic frameworks (MOFs), 10 and porous polymer networks (PNNs) 11 have been widely investigated and exhibited good separation performance.…”
