Construction of FeSbO4-Sb2O4 hetero-nanocrystals anchored on reduced graphene oxide sheets for superior lithium and sodium storage

Nanoconfinement of ultra-small Bi2Te3 nanocrystals on reduced graphene oxide: a pathway to high-performance sodium-ion battery anodes

“…2G shows the O 1s spectra of Bi 2 Te 3 /rGO, where the three fitted peaks at 533.1, 531.3, and 530.2 eV are attributed to the C–O–C, Bi–O–C, and Bi–O bonds, respectively. 29,30 It is worth noting that the Bi–O–C chemical bond between rGO and Bi 2 Te 3 facilitates rapid charge transfer while maintaining good morphological and structural stability. The 4f 5/2 and Bi 4f 7/2 inherent peaks (Fig.…”
