Porphyrin-Based Hyper-Cross-Linked Polymers as Adsorbents for Reversible Capture of Iodine

ACS Sustainable Chemistry & Engineering, Год журнала: 2024, Номер 12(32), С. 12113 - 12125

Designing a novel adsorbent with high selectivity and absorptive capacity to remove I2 remains challenging task. In this work, series of porphyrin-based hyper-cross-linked porous organic polymers (PHCPs) dual hydroxy-rich structure were synthesized by the Friedel–Crafts reaction. PHCPs exhibit excellent thermal stability. The incorporation abundant π-electrons heteroatoms (N/O) in framework leads substantial charge transfer interactions iodine, resulting adsorption (469 mg g–1) rapid adsorption. Moreover, dynamics for iodine both aqueous cyclohexane solutions follow pseudo-second-order kinetic model, isotherm model complies Freundlich model. Importantly, selectively capture I3– presence anionic competition effectively at different pH values. Additionally, volatile performance reached 623 wt %. This study highlights extensive application prospects removal from gas liquid phases.

In this research, two types of metal-free organic–inorganic phosphazene based hybrid porous polymers (HPMs) enriched with phosphorus (P) and nitrogen (N) for gas sorption characteristics were reported. Cyclic phosphazenes synthesized by condensation biphenyl methanol the hexachlorocyclophosphazenes (HCCPs) followed cross-linking fabrication high surface area moiety designated as HCP-1. Whereas HCP-2 was replacement polydichlorophosphazene (PDCP) chlorines later cross-linked in same manner. Brunauer–Emmett–Teller areas (SABETs) HCP-1 482 323 m2 g–1, respectively, whereas pore size distribution under 1.10 nm. The observation a higher is strongly indicative cyclic N P long chain backbone [-N═P-]. represented carbon dioxide (CO2) adsorption (1.656 mmol g–1 quantity adsorbed 37.13 cm3 at 273 K/1 bar 1.35 30.37 298 bar). low showed moderate capacity (1.6 35.82 1.26 28.36 values iodine uptake are 148 227 wt %, 353 K. These results indicate facile convenient method to synthesize heteroatom-rich CO2 I2 applications.

Efficient and Selective Removal of Iodine in Aqueous Media Using Morphology-Controlled Porous Hyper-Cross-Linked Polymers

ACS Applied Polymer Materials, Год журнала: 2025, Номер 7(3), С. 1639 - 1650

Опубликована: Янв. 30, 2025

Hyper-cross-linked polymers (HCPs) have demonstrated great potential for capture, catalysis, drug delivery, and energy storage attracted extensive research interest. Nevertheless, tuning their nanoscale morphology remains a challenge. Herein, we constructed series of HCPs (HCP[HaPb]) with various morphologies (nanospheres, nanorod-like, flower-like nanostructures) by controlling the molar ratios monomers hexakis(benzylthio)benzene quality. In addition, HCP[H200P3] rich nitrogen sulfur atoms showed fast adsorption rate high capacity I3– in aqueous media. The reached 98% within 5 min at liquid/solid ratio 1 mL mg–1, saturated 1.388 g g–1 was obtained 30 mg–1. Additionally, flow-through experiments revealed that an impressive removal flow 1.0 min–1. More importantly, could selectively capture presence competing anions. This work proved adsorbent highly selective has good prospects practical application I3–.
