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 nitrogen (N 2 ) electro-reduction to ammonia (NH 3 ) at ambient conditions is considered a promising substitute for the Haber−Bosch (H−B) process. Considering the low Faradaic efficiency (FE) and slow reaction kinetics of the nitrogen reduction reaction (N 2 RR), it is important to design robust catalysts that can address the above-mentioned challenges. A boron-enriched hyper-cross-linked polymer (Poly-BBA) based on benzene boronic acid synthesized by a fast microwave-assisted approach has reportedly been used as metal-free electrocatalyst for efficient N 2 electro-reduction to NH 3 . The Poly-BBA was synthesized using microwave power of 400 W at 45 °C for 30 min and aging at 100 °C for 30 min. The successful synthesis of Poly-BBA was conducted by state-of-the-art analytical techniques. The N 2 sorption analysis demonstrates a hierarchical porous structure with a high SA BET of 1080 m 2 g −1 and a total pore volume of 0.7 cm 3 g −1 . The Poly-BBA shows selective reduction of N 2 to NH 3 with an FE of 21.9% in 0.05 M H 2 SO 4 solution at −0.5 V vs RHE. The presence of boron in the synthesized material resulted in the redistribution of electron density and provided electrondeficient sites for adsorption and activation of N 2 molecules.
