Hypercrosslinked ionic polymers constructed by ionic cross-linkers and Bronsted acid for catalytic cycloaddition of low-concentration CO2 with epoxide under atmospheric pressure
The capture and conversion of low-concentration CO2 into high value-added products under mild conditions remains a major challenge. In this work, an additive/metal/solvent-free catalytic transformation between epoxides and low-concentration CO2 under atmospheric conditions is achieved by using hypercrosslinked ionic polymers (IMPy-HIP or BPy-HIP) as catalysts prepared by an one-pot Friedel–Crafts alkylation between an imidazolium-based ionic linker and 1, 1′-binaphthyl-2, 2′-diyl hydrogenphosphate (BNDHP, a Bronsted acid, strong hydrogen bond donor). The HIPs bearing a strong hydrogen bonding site (ArPO3OH), active cations (imidazolium) and nucleophilic counterion (Cl−) demonstrate highly catalytic efficiency and stable recyclability for low-concentration CO2-epoxide cycloaddition. The experiment results combining with DFT theoretical calculations reveal that the high performance of this catalyst attributes to the cooperation of the Bronsted acid site (P-OH), basic pyridine N and ionic site. In addition, the catalyst shows excellent structural stability and substrate universality, and it can be easily separated by centrifugation and reused for five runs without significant decrease in catalytic performance.
期刊介绍:
Separation and Purification Technology is a premier journal committed to sharing innovative methods for separation and purification in chemical and environmental engineering, encompassing both homogeneous solutions and heterogeneous mixtures. Our scope includes the separation and/or purification of liquids, vapors, and gases, as well as carbon capture and separation techniques. However, it's important to note that methods solely intended for analytical purposes are not within the scope of the journal. Additionally, disciplines such as soil science, polymer science, and metallurgy fall outside the purview of Separation and Purification Technology. Join us in advancing the field of separation and purification methods for sustainable solutions in chemical and environmental engineering.
