The impact of GO loading concentration on the electrochemical performance of the nanocomposites was investigated. The reaction follows a diffusion substitution pathway, gradually transforming Bi₂O₃ powder into Bi₂S₃ nanostrips, concurrently converting GO into rGO. Enhanced specific capacitances were observed across all nanocomposite samples, with the Bi₂S₃@0.2rGO exhibiting the highest specific capacitanceRSC advances12313-12322https://www.ebi.ac.uk/biostudies/studies/S-EPMC11019906biostudies-literatureSolid state engineering of Bi₂S₃/rGO nanostrips: an excellent electrode material for energy storage applications.PMC11019906Kate RSArote SAArbuj SSBhattacharjee KAutade VBKale BBKalubarme RSApte SKfalseSolid state engineering of Bi₂S₃/rGO nanostrips: an excellent electrode material for energy storage applications.The study presents a novel, one-pot, and scalable solid-state reaction scheme to prepare bismuth sulphide (Bi₂S₃)-reduced graphene oxide (rGO) nanocomposites using bismuth oxide (Bi₂O₃), thiourea (TU), and graphene oxide (GO) as starting materials for energy storage applications.
