“…The diffusion convection current steadily increases with increased rotation rates, indicating a greater oxygen flux towards the disc electrode even while the onset potential did not change. 90,91 The Koutecky-Levich (K-L) equation was used to calculate the number of electrons transported (n) per oxygen molecule engaged in the ORR at the AgCoS@MXene electrode:…”

In this work, we present a highly effective electrode material (AgCoS@MXene) for supercapattery device application that is produced hydrothermally. We examined the morphology and crystallinity of the synthesized materials using SEM and XRD studies. The synthesized compounds were subjected to a thorough electrochemical performance study employing a three-electrode configuration in a 1 M KOH electrolyte. AgCoS@MXene demonstrated an exceptional Qs of 943.22 C/g at a current density of 2.0 A/g. We formed a supercapattery device (AgCoS@MXene//AC) with AgCoS@MXene as the positive electrode and activated carbon (AC) as the negative electrode. The supercapattery device was demonstrated to have a high specific capacity of 315.22 C/g, a power density of 1275 W/kg, and an energy density of 35.94 Wh/kg. In addition, 5000 charging and discharging cycles were used to assess the device's long-term longevity. The findings indicated that the device preserved nearly 82% of its initial capacity. Besides, the hybrid electrode is used for the electrocatalytic activity for the oxygen reduction reaction

In this paper, a novel nano-electrocatalyst (Pt@N-CDs/RGO) with reduced graphene oxide as the carrier and platinum (Pt) and nitrogen-doped carbon quantum dots (N-CDs) together as the active sites was prepared by a simple hydrothermal method. By comparing the electrochemical properties of commercial platinum carbon (Pt/C) and Pt@N-CDs/RGO at 20% wt Pt, it was found that Pt@N-CDs/RGO exhibited excellent ORR properties, such as an onset potential (Eonest ) of 1.10 V, a half-wave potential (E1/2) of 0.82 V, a limiting current density of 5.06 mA/cm2, and a number of transferred electrons as high as 3.97. By using the chronoamperometric method (CA) to cycle for 10000 s, it was found that the stability of both, Pt@N-CDs /RGO maintains 18% activity after a cycle of 10000 seconds, which is much higher than Pt/C. The study showcased a new efficient and durable catalyst for PEMFCs.
