“…4C). Two new peaks at 523 cm À1 and 438 cm À1 appeared in the FT-IR spectroscopy of Se@CNFs-CNT, which are correspondences to the torsion of ring in which a CeSe bond is contained and the bending vibration of CeSe bond, respectively [43,44,46].…”

“…After heating at high temperature with CNFs-CNT (or CNFs), three characteristic peaks at 198, 231 and 288 cm À1 were obtained for both Se@CNFs-CNT and Se@CNFs. The peaks at 198 and 288 cm À1 can be ascribed to CeSe stretching vibration and the CeSeeSe group vibration [43,44]. Fig.…”

“…The binding energies of Se 3d 5/2 and 3d 3/2 in Se@CNFs-CNT are located at 55.4 and 56.3 eV, respectively. Compared to Se, the higher binding energies of Se 3d 5/2 and 3d 3/2 inSe@CNFs-CNT reveal the formation of chemical bonds between Se and other atoms [34,43,44,46,47]. Thermogravimetry (TG) analyses reveal that the selenium contents of the Se@CNFs-CNT and Se@CNFs are 35% and 27%, respectively (Fig.…”

“…4c displays the FT-IR spectra of the CPAN and CPAN/Se. 50 Both the CPAN and the CPAN/Se exhibit peaks at 1590, 1295, and 833 cm -1 corresponding to the C=C bond, C=N bond, and C-N bond, respectively, [16][17][18][19] suggesting the formation of a heterocyclic compound in the carbonization process. The new peak at 523 cm -1 corresponds to torsion of rings in which a C-Se 55 bond is contained, 20 and the peak located at 438 cm -1 could be also attributed to the C-Se bending vibration, 19 indicating the formation of C-Se bonds after the dehydrogenation and cyclization process.…”

Guo, Z. (2014). A novel type of one-dimensional organic selenium-containing fiber with superior performance for lithium-selenium and sodium-selenium batteries. RSC Advances: an international journal to further the chemical sciences, 4 (106), 61673-61678. A novel type of one-dimensional organic selenium-containing fiber with superior performance for lithium-selenium and sodium-selenium batteries AbstractA novel type of organic selenide fiber composed of carbonized polyacrylonitrile/selenium (CPAN/Se) has been synthesized by heating polyacrylonitrile-selenium (PAN-Se) fibers via the electrospinning technique at 600°C. The Se molecules are confined by N-containing carbon ring structures in the form of energy-storing selenium side chains in the carbonized PAN matrix. This unique stable chemical structure with a conductive carbon skeleton connected to the selenium side chains and excellent mechanical stability can allow CPAN/Se composite cathodes to be charged and discharged in a low-cost carbonate-based electrolyte with excellent long cycle stability and quite good rate performance. The superior electrochemical performance of CPAN/Se electrodes is demonstrated in both lithium-ion and sodium-ion batteries, where they have delivered a high capacity of nearly 600 mA h g-1 for 500 cycles in lithium-selenium (Li-Se) batteries and 410 mA h g-1 for 300 cycles in sodium-selenium (Na-Se) batteries at 0.3 C, respectively. lithium-selenium (Li-Se) batteries and 410 mAh g -1 for 300 cycles in sodium-selenium (Na-Se) batteries at 0.3 C, respectively.
