Perovskite-type RCoO3 (R = Pr, Eu, Gd) nanofibers for supercapacitor electrodes and antiferromagnet

In situ synthesis of europium oxide (Eu2O3) nanoparticles in heteroatom doped carbon nanofibers for boosting the cycling stability of supercapacitors

“…26 Specifically, EuCoO 3 nanofibers synthesized by Luo et al had a typical pseudocapacitive feature and showed a capacitance of 133 F g −1 at 1 A g −1 . 27 Aryanrad et al developed a Eu 2 O 3 nanorod/RGO nanocomposite, achieving a specific capacity of 403 F g −1 . 28 In another study, Naderi et al reported that Eu 2 O 3 NP-RGO had a specific capacitance of 313 F g −1 at 2 mV s −1 and 268 F g −1 at 2 A g −1 .…”
