Development of nano-spherical RuO2 active material on AISI 317 steel substrate via pulse electrodeposition for supercapacitors

Unveiling the Influence of Organic Chain Length on the Physical Properties of Two-Dimensional Cobalt-Based Hybrid Perovskites

“…This finding indicates that BA 2 CoCl 4 demonstrated better ionic conductivity with a smaller charge-transfer resistance than the other samples. A smaller semicircle diameter may have the potential to be used as high-rate power sources . The Nyquist spectrum of BA 2 CoCl 4 is subsequently fitted with the equivalent circuit fitting method (see Figure b) composed of two Randle circuits and a Warburg impedance, indicating that two electrochemical processes occurred within the perovskites.…”

Pulse electrodeposited RuO2 electrodes for high-performance supercapacitor applications

“…The electrolyte pH was adjusted by using 0.1 M H 2 SO 4 till it reached pH 3. For comparison, the RuCl 3 electrolyte was also used, the electrolyte composition and deposition condition being identical to those reported in an earlier work [23]. All the chemicals were purchased from Alfa Aesar.…”

“…For example, the surface morphology of the deposit can be tailored by adjusting the electrochemical parameters such as the deposition mode, applied potential, current density, the cell on or off time and duration of deposition [22]. Recently, we have reported the synthesis of a hydrous RuO 2 electrode on Ni-flashed AISI 317 stainless steel substrate using galvanostatic pulse electrodeposition method exhibits nano-spherical morphology [23]. Very few researchers have explored ruthenium compounds other than RuCl 3 for the preparation of ruthenium oxide electrodes through electrodeposition [24] and RuNS was only used for thermal synthesis in order to obtain a chloride-free catalyst [25].…”
