“…The removal of RB from aqueous solutions surpassed all other materials, while the removal of NR and MO were comparable to state-of-the-art separation performances. The IAST selectivity of the HCP was calculated to model CO 2 capture from a coal-fired flue gas mixture (15% CO 2 and 85% N 2 ) at 298 K. , Due to the low N 2 uptake, the CO 2 /N 2 selectivity of our Styrofoam-based HCP material exceeded those of other materials currently used in this application. The results indicate that the Styrofoam-based HCPs could potentially be successfully utilized in CO 2 capture and water purification applications.…”

The synthesis of hyper-cross-linked polymers (HCPs) is typically achieved using costly reagents. This study demonstrates the utilization of a plastic waste, Styrofoam, to create a series of HCPs through a one-pot Friedel−Crafts reaction. The influence of substrate, catalyst, and cross-linker ratio was investigated to yield HCPs with Brunauer−Emmett−Teller (BET) surface areas up to 1199 m 2 /g. We exploited this recyclate HCP for carbon capture from flue gas, dye removal, and As(V) sequestration from water. The adsorption capabilities of this cost-effective adsorbent were comparable to and surpassed current state-of-the-art nanoporous materials such as metal−organic frameworks (MOFs), activated carbon, zeolites, and other HCPs.

“…The zeolite RX has a Si/Al ratio of around 1.27 and the aluminium atom present in the framework structure creates a negative charge and they are balanced by the alkali cation (Na + ) present in the zeolite framework which causes the high adsorption of CO 2 molecules. 9,25 The BET plots for the synthesized zeolite RA and RX are given in Fig. 23.…”

“…The presence of channels in the mesoporous silica framework structure helps in the rapid gas diffusion process. 9 The attraction of CO 2 towards the silica surface is low compared to the attraction of CO 2 by other solid adsorbents such as MOF and zeolite and this is due to the absence of cationic sites in the mesoporous silica framework structure. 2,9 Currently, many researchers are trying to overcome the above problems by using high adsorption and better CO 2 selective process and economically viable materials.…”

“…Concerns about the link between increases in the concentration of SO 2 , CO 2 , and CH 4 in the atmosphere and global climate changes have led to extensive research in limiting the emissions of harmful gases 16 . Numerous studies have been conducted to investigate methods of adsorption using nanoporous solids for the sequestration of toxic gases 17,18 . Modification of nanofiber surface through the addition of nanoporous materials become one of the interesting strategies for the improvement of harmful gases capture ability in nanofiber filter media 6,17 …”

Distribution of particulate matter (PM), toxic, and greenhouse gases in the atmosphere are responsible for air pollution, human health issues, and enhanced global warming. Traditional polymeric nanofibers only can remove PMs from air flue. The objective of this study was to investigate the adsorption capacity and selectivity of hybrid nanofibrous filter media based on polyacrylonitrile (PAN) with different percentages of activated carbon particles such as gas adsorbent for removal of sulfur dioxide (SO2), carbon dioxide (CO2), and methane (CH4) from gaseous streams The adsorption isotherms of SO2, CO2, and CH4 on the hybrid samples were measured at 298, 323, and 348 K and with a pressure range of 0–21 bar by means of the volumetric adsorption method. Uniform PAN nanofiber filter (PANNF) with an average diameter of 273 nm was achieved via the electrospinning process after the optimization of different parameters. Waste tea‐derived activated carbons (ACs) by using phosphoric acid as the activation agent was synthesized through two different methods, chemical activation to obtain the micro size of AC (MAC), and microwave radiation energy to obtain nano size of AC (NAC). Hybrid nanofibers were functionalized with dispersing homogenous solutions containing AC particles by the electrospray process. The effect of high and low loading of NAC and MAC on the PANNF surface was studied to increase our understanding about gas adsorption properties of prepare samples. The samples were characterized by Image analysis (ImageJ), Statistical package for social science (SPSS), Scanning electron microscopy (SEM), X‐ray diffraction (XRD), Fourier transform infrared (FT‐IR), Energy‐Dispersive x‐ray (EDX), and Nitrogen adsorption/desorption isotherms.
