“…Figure 5 represents a schematic demonstration of the synthesis process of core−shell structured CMPs/CPPs. CMPs can be well identified as the most efficient POMs for the separation of CO 2 greenhouse gas due to their noteworthy advantages including high surface area and tunable properties ( Reddy et al, 2021 ; Zhang et al, 2023 ). The importance of CMPs is because of the necessary bond conjugation and amorphous morphology.…”

Over the last decades, porous organic materials (POMs) have been extensively employed in various industrial approaches including gas separation, catalysis and energy production due to possessing indisputable advantages like great surface area, high permeability, controllable pore size, appropriate functionalization and excellent processability compared to traditional substances like zeolites, Alumina and polymers. This review presents the recent breakthroughs in the multifunctional POMs for potential use in the membrane-based CO2 separation. Some examples of highly-selective membranes using multifunctional POMs are described. Moreover, various classifications of POMs following with their advantages and disadvantages in CO2 separation processes are explained. Apart from reviewing the state-of-the-art POMs in CO2 separation, the challenges/limitations of POMs with tailored structures for reasonable application are discussed.

“…Conjugated microporous polymers (CMPs) have emerged as promising materials for CO 2 capture due to their high surface area, porous structure, and tunable properties. 7–9 The significance of CMPs comes with the essential bond conjugation and amorphous morphology under microporous organic polymers (MOPs). Poly(arylene ethynylene)s were reported in 2007 as the first synthesized CMPs under palladium-catalyzed Sonogashira–Hagihara coupling by Cooper and his coworkers.…”

This study explores the modification of pore structures in porous silica materials synthesized using sodium silicate and waste gelatin, under varying silica‐to‐gelatin ratios. At ratios of 1.0–1.5, bimodal porous silica with mesopores and macropores emerged due to spaces between silica nanoparticles and clusters, following gelatin elimination. The study further evaluated the obtained bimodal porous silica as polyethyleneimine (PEI) supports for CO2 capture, alongside PEI‐loaded unimodal porous silica and hollow silica sphere for comparison. Notably, the PEI‐loaded bimodal silica showcased superior CO2 uptake, achieving 145.6 mg g−1 at 90 °C. Transmission electron microscopy (TEM) revealed PEI′s uniform distribution within the pores of bimodal silica, unlike the excessive surface layering seen in unimodal silica. Conversely, PEI completely filled the hollow porous silica‘s interior, extending gas molecule diffusion distance. All sorbents displayed nearly constant CO2 adsorption across 20 cycles, demonstrating outstanding stability. Notably, the bimodal porous silica displayed a negligible capacity loss, underscoring its robust performance.
