Synthesis of a New Porous Organic Polymer for Efficient CO ۲ Capture

One of the main causes of climate change and global warming is the rising of carbon dioxide (CO ۲) in the atmosphere. In response to this issue, there has been a global effort to develop various technologies for CO ۲ adsorption. Porous organic polymers (POPs) are a crucial type of organic porous materials that have shown significant promise as CO ۲ sorbents. The unique properties of these porous materials such as flexible structure, excellent thermal and chemical stability, permanent porosity, and low density, make them ideal options for efficient CO ۲ capture. In this study, a Phloroglucinol-based porous organic polymer (Ph-POP) was successfully created through a catalyst-free Schiff base condensation process involving ۴,۴'-oxydianiline and a novel trisaldehyde in dimethylformamide (DMF) under solvothermal conditions. The structural properties of Ph-POP were characterized using different methods including Fourier-transform infrared spectroscopy (FT-IR), X-ray powder diffraction (XRD), field emission scanning electron microscope (FE-SEM), energy-dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM), thermogravimetric analysis (TGA), vibrating sample magnetometry (VSM) and Brunauer-Emmett-Teller (BET) surface area analysis. This porous polymer contains a high heteroatom (N and O) content, providing accessible basic sites for CO ۲ adsorption. This porous organic polymer showed a CO ۲ adsorption capacity of ۵۴.۱۸ cm۳ g-۱ at ۲۷۳ K and ۳۹.۴۹ cm۳ g-۱ at ۲۹۸ K under ۱ bar pressure, respectively. This research aims to introduce a porous organic polymer as an efficient adsorbent for capturing gas pollutants and their potential incorporation in nanocomposites and membranes. This could offer a promising solution to combat atmospheric pollutions and global warming.
