Homi Bhabha Road, Pune, India. E-mail: k. E-mail: r. These are the C 3 symmetric C O groups resulting from the enol to keto tautomerism and the C 2 symmetric C O group from electrochemically oxidized hydroquinone linker 8 Fig. The hexagonal 2D lattice enriched with a large number of C O groups, stacked with an interlayer distance of 3. Also, the crystalline honey-comb structure of HqTp provides a unique pore size of 1.
Then, we have characterized the electrodes, followed by washing with water. After charging up to 1. This has been confirmed by the observation of a new stretching vibrational peak formed at When the system is discharged to 0.
Still, a diligent observation shows the presence of a very weak stretching peak at the C O region of the discharged cathode which indicates that the first cycle of discharging is not sufficient for the full utilization of the C Os in the framework. Additionally, to figure out the efficiency of the COF based organic cathode, we have strategically performed chargeβdischarge cycles for a cell.
After complete discharging up to 0. It showcases a down field chemical shift of the C O peak from The X-ray photoelectron spectroscopy XPS provides information about the chemical state of the concerned elements in the pristine, charged, and discharged conditions of HqTp. Moreover, the ex situ analysis is extended to electronic imaging techniques with elemental mapping.
It also displayed the presence of carbon nanofiber CNF which has been used as an electrical conductivity amplifier in the cathode.
