Evaluation of Schiff-Base Covalent Organic Frameworks for CO2 Capture: Structure-Performance Relationships, Stability, and Performance under Wet Conditions

Yuxiang Wang et al.

Summary: This study evaluates a series of Schiff-base COFs with different functionalities, pore sizes, and framework dimensions for potential applications in postcombustion CO2 capture. It is found that COFs undergoing enol-to-keto transformations outperform other studied COFs, and CO2 uptake capacity of a COF is not necessarily a function of its pore aperture and specific surface area.ropicity.

Efficient N-Doped Porous Carbonaceous CO2 Adsorbents Derived from Commercial Urea-Formaldehyde Resin

Jiamei Huang et al.

Summary: Porous carbons with abundant availability and tunable physical properties have attracted tremendous interest for CO2 capture application. However, their insufficient CO2 utilization performance due to the poor active sites on their surface is a drawback. In this study, we report the fabrication of N-rich porous carbon derived from urea-formaldehyde resin via a two-step synthetic route involving physical carbonization and KOH activating. The optimized sample with 9.87 wt% N exhibits notable CO2 uptake capacities and high selectivity efficiency, attributed to advanced textural properties and incorporation of nitrogen into carbon surfaces.

High CO2 adsorption on amine-functionalized improved macro-/mesoporous multimodal pore silica

Huangyu Yan et al.

Summary: In recent years, amine functionalized materials have attracted great interest as prospective solid adsorbents for CO2 capture. However, the amine functionalization of traditional supports can lead to a decrease in the pore volume and specific surface area, affecting the CO2 adsorption-desorption kinetics. In this study, macro-/mesoporous multimodal pore silica was synthesized using a ternary nonionic surfactant as a template and impregnated with TEPA to overcome this issue. The resultant HMS-4h support exhibited bimodal pores, high surface area and large pore volume, leading to improved dispersibility of TEPA and reduced diffusion resistance of CO2. The highest adsorption capacity reached 6.04 mmol/g and remained steady after 10 adsorption-desorption cycles. The research provides valuable insights for the design of high-performance solid amine CO2 adsorbents in the future.
