The rapid development of nuclear energy posed a great threat to the environment and human health. Herein, two hydroxyl-functionalized hyper-crosslinked polymers (PIHCP-1 PIHCP-2) containing different electron active sites have been synthesized via Friedel-Crafts alkylation reaction polyimides. resulting showed micro/mesoporous morphology good thermal chemical stability. Rely on high porosity multi-active sites, PIHCPs show an ultrahigh iodine uptake capacity reached 6.73 g g−1 removal efficiency from aqueous solution also reaches 99.7%. Kinetic analysis demonstrates that adsorption was happened heterogeneous surfaces in form multilayer chemisorption. Electrostatic potential (ESP) calculation proves contribution hydroxyl groups capture performance. In addition, both adsorbents can be maintained over 91% after four cyclic experiments which ensures their recyclability for further practical applications.

Cost-Effective Synthesis of Carbazole-Based Nanoporous Organic Polymers for SO₂ Capture

ACS Applied Materials & Interfaces, Год журнала: 2025, Номер unknown

Опубликована: Янв. 29, 2025

Sulfur dioxide (SO2), a pervasive air pollutant, poses significant environmental and health risks, necessitating advanced materials for its efficient capture. Nanoporous organic polymers (NOPs) have emerged as promising candidates; however, their development is often hindered by high synthesis temperatures, complex precursors, limited SO2 selectivity. Herein, we report room-temperature, cost-effective of carbazole-based nanoporous (CNOPs) using 1,3,5-trioxane paraldehyde, offering advancement over traditional Friedel-Crafts alkylation methods. The resulting CNOPs exhibit surface area up to 842 m2·g-1 feature ultramicroporous structures optimized adsorption. At 298 K 1 bar, the demonstrated adsorption capacities 9.39 mmol·g-1. Ideal adsorbed solution theory (IAST) calculations revealed outstanding selectivities 105 SO2/CO2 6139 SO2/N2 mixtures, supported breakthrough experiments demonstrating superior separation performance. This work not only provides straightforward synthetic route but also offers valuable insights into design porous tailored enhanced capture, addressing critical challenges.
