Synthesis of Tungsten Disulfide on B-N-Doped Carbon Nanotubes to Enhance the Electrochemical Performance of SupercapacitorsYEŞİLBAĞ, Yaşar ÖzkanYesilbag, Fatma Nur TuzlucaHuseyin, AhmadSalih, Ahmed Jalal SalihFizikUygulamalıNanobilim ve NanoteknolojiAtomik ve Moleküler KimyaKimyaEnerji ve YakıtlarMalzeme BilimleriÖzellik ve TestMühendislikIn this research, boron and nitrogen-doped carbon nanotubes (B-N-CNTs) were synthesized at 900°C using the FCCVD method. Carbon, nitrogen, and boron as source materials were simultaneously introduced using a batch- mode droplet reactor and ferrocene as a catalyst. B-N-CNTs were obtained with diameters ranging from 10 - 50 nm and lengths around 30 – 80 μm. These B-N-CNTs were thoroughly characterized and structurally analyzed. Subsequently, tungsten disulfide (WS2) nanosheets on B-N-CNTs were synthesized using the hydrothermal method to design a composite material and were investigated as electrodes for supercapacitors. The morphological properties of B-N-CNT@WS2 were determined by various analytical techniques such as XRD, FESEM, XPS, and EDS. B-N-CNT@WS2 was investigated as an electrode for supercapacitors in two- and three-electrode cells. In the three-electrode cell, B-N-CNT@WS2 exhibited a specific capacitance of 320 F g−1 at a current density of 0.5 A g−1, while the two-electrode cell showed a capacitance of 41 F g−1. The symmetric supercapacitor at a current density of 5 A g−1 exhibited excellent structural stability by preserving 90% of its specific capacitance after 9000 cycles in the 1 V potential range.2024Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/17742https://doi.org/10.18185/erzifbed.15173461307-9085enErzincan Üniversitesi Fen Bilimleri Enstitüsü Dergisiinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/17742
