“…According to the GO’s XRD pattern a sharp diffraction peak at 2θ = 10.9 ◦ is related to the crystalline nature of the GO 35 . The XRD pattern of the chitosan sample exhibited two diffracted peaks near the 2θ = 9.9 ◦ and 2θ = 20.8°, which are attributed to the crystalline structure of commercial chitosan sample (JCDPS no.39-1894) 58 . Considering the XRD pattern of the CTS/GO/ZnO composite, it can be observed that some characteristic peaks have appeared at the 2θ quantities equal to 31.6° , 34.7°, 36.1° and 47.5°.…”

“…The sharp elevation of global warming has already resulted in several negative environmental impacts and poses a severe threat to human survival 4 . Diverse CO 2 capture techniques are utilized within industrial processes, including solvent-based absorption, solid sorbent-based adsorption 5 , membrane processes, and cryogenic separation processes 6 . Of these techniques, CO 2 absorption using alkali solution and cryogenic approaches present economic impediments that arise from issues such as solvent loss, corrosion risks, elevated pressure and temperature requirements, and significant energy consumption needed for refrigeration purposes 7 .…”

This study was deeply focused on developing a novel CTS/GO/ZnO composite as an efficient adsorbent for CO2 adsorption process. To do so, design of experiment (DOE) was done based on RSM-BBD technique and according to the DOE runs, various CTS/GO/ZnO samples were synthesized with different GO loading (in the range of 0 wt% to 20 wt%) and different ZnO nanoparticle’s loading (in the range of 0 wt% to 20 wt%). A volumetric adsorption setup was used to investigate the effect of temperature (in the range of 25–65 °C) and pressure (in the range of 1–9 bar) on the obtained samples CO2 uptake capability. A quadratic model was developed based on the RSM-BBD method to predict the CO2 adsorption capacity of the composite sample within design space. In addition, CO2 adsorption process optimization was conducted and the optimum values of the GO, ZnO, temperature, and pressure were obtained around 23.8 wt%, 18.2 wt%, 30.1 °C, and 8.6 bar, respectively, with the highest CO2 uptake capacity of 470.43 mg/g. Moreover, isotherm and kinetic modeling of the CO2 uptake process were conducted and the Freundlich model (R2 = 0.99) and fractional order model (R2 = 0.99) were obtained as the most appropriate isotherm and kinetic models, respectively. Also, thermodynamic analysis of the adsorption was done and the ∆H°, ∆S°, and ∆G° values were obtained around − 19.121 kJ/mol, − 0.032 kJ/mol K, and − 9.608 kJ/mol, respectively, indicating exothermic, spontaneously, and physically adsorption of the CO2 molecules on the CTS/GO/ZnO composite’s surface. Finally, a renewability study was conducted and a minor loss in the CO2 adsorption efficiency of about 4.35% was obtained after ten cycles, demonstrating the resulting adsorbent has good performance and robustness for industrial CO2 capture purposes.

Deep eutectic solvents (DES) are a generation of ionic liquids that benefit from low cost, good stability, and environmental-friendly features. In this research, a porous silica gel was impregnated with a eutectic Choline Chloride-Monoethanolamine solvent (ChCl-MEA) to greatly improve its CO2 capture performance. In the impregnation, the weight percentages of ChCl-MEA were used in the range of 10–60 wt% at a temperature of 25 °C. The effect of ChCl-MEA loading on the structural properties of the DES-modified silica samples was studied by BET, FTIR, and TGA analyses. Investigation of the CO2 adsorption performance at different operational conditions showed that the modified silica gel with 50 wt% ChCl-MEA (Silica-CM50) presents the highest CO2 capture capacity of 89.32 mg/g. In the kinetic modeling, the fractional order model with a correlation coefficient of 0.998 resulted in the best fit with the experimental data. In addition, the isotherm data for Silica-CM50 were well-fitted with the Dual site Langmuir isotherm model with a correlation coefficient of 0.999, representing two distinct sites for the adsorption process. Moreover, the thermodynamic parameters including Enthalpy, Entropy, and Gibbs free energy at 25 °C were obtained to be − 2.770, − 0.005 and − 1.162, respectively. The results showed the exothermic, spontaneous and feasibility of the adsorption process.

The increase in waste generation from food processing and agricultural residues presents a significant challenge for sustainable development and waste management. Utilizing these biomass waste materials for valuable applications can help address this issue, while promoting a circular economy. In this context, the current study focuses on the valorization of waste materials of organic origin for CO 2 capture, a crucial component in global efforts to mitigate climate change and reduce the planet's warming. The investigated polymeric aerogels were synthesized using byproducts from food processing and agricultural residue waste products, specifically crustacean shells and sugarcane bagasse. A comprehensive set of analytical techniques, including viscometry, Fourier transform infrared spectroscopy (FTIR), energy dispersive X-ray spectroscopy (EDX), thermogravimetric analysis (TGA), X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and Brunauer−Emmett−Teller (BET) surface area analysis, were employed to examine the physicochemical, thermal, microstructural, and textural properties of the prepared materials. These adsorbents demonstrated promising prospects for carbon dioxide capture, adsorbing up to 5.78 mg/g of the gas at 273 K and 2.82 mg/g at 298 K. Considering their sorption performance, the low cost of raw materials, and the potential for scaling up, this work further validates the adsorbent-based postcombustion carbon capture technology as an effective approach for addressing the detrimental consequences of carbon dioxide emissions.
