The development of efficient catalysts for the catalytic conversion of CO 2 is extremely important in the process of CO 2 chemistry. In this work, a Zn-based coordination polymer (ZnBr 2 -CP) was synthesized from a tridentate pyridine ligand bearing an imidazolium salt ligated with ZnBr 2 . It possesses not only the high activity of homogeneous catalysts but also the recoverable features of heterogeneous catalysts. More importantly, configured double active sites allow the catalyst ZnBr 2 -CP to exhibit excellent activity in the cycloaddition of CO 2 with epoxides under solvent-and co-catalyst-free conditions, achieving yields as high as 99% for a variety of cyclic carbonates at 80 °C for 24 h. This study provides insight into the design of efficient catalysts for conversion of CO 2 .

Phenanthrene, a prime polycyclic aromatic hydrocarbon (PAH) pollutant, is utilized to develop a nanoporous hypercrosslinked polymeric adsorbent (poly-PHEN-C) through the microwave-assisted process from catalyst anhydrous AlCl 3 and solvent CHCl 3 . Nanoporous poly-PHEN-C proves to be a highly effective adsorbent for adsorbing CO 2 from flue gas and removing organic dyes from wastewater. CO 2 capture capacity of 3.2 mmol g −1 at 298 K and 1 bar is ascribed to the combined effect of surface area (1472 m 2 g −1 ), micropores (1.1, 1.7 nm), pore volume (0.73 cm 3 g −1 ), and π electrons. The separation selectivity of the gas mixture, i.e., CO 2 /N 2 (15:85), is estimated from the ideal adsorbed solution theory model. Moreover, poly-PHEN-C is employed for removal of cationic (crystal violet, CV) and anionic (alizarin red S, ARS) dyes from aqueous solutions. In the batch process, it exhibits adsorption capacities of 161 mg g −1 for CV and 120 mg g −1 for ARS. In the continuous fixed-bed column process, breakthrough capacity of 300 mg g −1 is achieved for CV. Thus, the present study offers an eco-friendly approach for effectively managing three categories of hazardous pollutants, namely, PAHs, greenhouse gas CO 2 , and organic dyes, a sustainable strategy for environmental management.

The development of efficient bifunctional organocatalysts for the catalytic conversion of CO 2 under mild conditions remains particularly challenging. Inspired by the synergistic mechanism of intramolecular Lewis acid-base active sites, we report a series of bifunctional cross-linked epoxy resin organocatalysts containing multiple active sites for the cycloaddition reaction of dilute CO 2 with epoxides. These catalysts exhibit high reactivity and product selectivity (10 examples, > 99 %) for the cycloaddition reactions of a variety of epoxides and CO 2 , and surprisingly, epichlorohydrin (ECH), can be converted under ambient temperature and pressure (25 °C, 1.0 bar) without co-catalysts. 1 H NMR, 13 C NMR, 19 F NMR and in situ IR studies suggest that the simultaneous and efficient activation of CO 2 and epoxides is responsible for the improved catalytic activity. Upon an insightful investigation of the catalytic mechanism, this protocol will contribute to the development of efficient and environmentally friendly metal-free catalysts.
