Strategic Design and Synthesis of Ferrocene Linked Porous Organic Frameworks toward Tunable CO2 Capture and Energy Storage

Abstract

This work focuses on porous organic polymers (POPs), which have gained significant global attention for their potential in energy storage and carbon dioxide (CO2) capture. The study introduces the development of two novel porous organic polymers, namely FEC-Mel and FEC-PBDT POPs, constructed using a simple method based on the ferrocene unit (FEC) combined with melamine (Mel) and 6,6′-(1,4-phenylene)bis(1,3,5-triazine-2,4-diamine) (PBDT). The synthesis involved the condensation reaction between ferrocenecarboxaldehyde monomer (FEC-CHO) and the respective aryl amines. Several analytical methods were employed to investigate the physical characteristics, chemical structure, morphology, and potential applications of these porous materials. Through thermogravimetric analysis (TGA), it was observed that both FEC-Mel and FEC-PBDT POPs exhibited exceptional thermal stability. FEC-Mel POP displayed a higher surface area and porosity, measuring 556 m2 g−1 and 1.26 cm3 g−1, respectively. These FEC-POPs possess large surface areas, making them promising materials for applications such as supercapacitor (SC) electrodes and gas adsorption. With 82 F g−1 of specific capacitance at 0.5 A g−1, the FEC-PBDT POP electrode has exceptional electrochemical characteristics. In addition, the FEC-Mel POP showed remarkable CO2 absorption capabilities, with 1.34 and 1.75 mmol g−1 (determined at 298 and 273 K; respectively). The potential of the FEC-POPs created in this work for CO2 capacity and electrical testing are highlighted by these results.

“…Supercapacitors (SCs), also referred to as ultracapacitors, are primarily categorized into three types based on the electrode material utilized. − The ability to store charge depends on the available surface area of the electrode, with a large surface area and very thin dielectric resulting in high capacitance values. − While the mechanism of charge storage in supercapacitors is similar to conventional capacitors, charges accumulate at the electrode’s surface, forming a double layer. In supercapacitors, the movement of ions is governed by electrostatic energy, and nonfaradic reactions predominate, as there is no transfer of electrons between the electrolyte and the electrode. ,− Capacitance in electrical double-layer capacitors (EDLC) is generated as electrons adhere to ions within the pores of the electrode material .…”

“…Paradoxically, even CP materials with substantial intrinsic charge storage capabilities may not lead to proportionate gains in overall storage capacity for the final device. Researchers have directed their attention toward the advancement of electrode material components and topologies in order to circumvent the limitations associated with supercapacitors [11][12][13][14] Porous organic polymers (POPs), such as CMPs, COFs, and CNTs, have garnered significant attention as electrode materials for electric double-layer capacitors (EDLCs). The incorporation of these materials brings forth numerous advantages, such as affordability, chemical stability, and widespread availability.…”
