“…R ct is mostly determined by the intrinsic features of the catalyst material, where a low R ct value suggests a quick reaction rate. It is known that a lower value of charge transfer resistance is associated with the higher electrocatalytic activity of electrodes for hydrogen generation 10 . The charge-transfer mechanism is broadly represented by a master equation from Volmer-Heyrovsky, which represents the widely accepted reaction mechanism for the HER in alkaline conditions 36 .…”

“…Within this framework, several catalysts have been investigated as potential electrode materials for the creation of renewable hydrogen. Due to their high electrocatalytic impact and low overpotentials for the Hydrogen Evolution Reaction (HER), most noble metals (in particular Pt), were the top choice materials [6][7][8][9][10][11] . Despite this, their exorbitant price and global scarcity have limited their vast usage.…”

This work reports the synthesis of poly (aniline-co-4-nitroaniline) deposited on a three-dimensional nanostructured nickel (3D-Ni) film, where both layers were fabricated via potentiostatic electrodeposition. The obtained electrocatalyst exhibited excellent electrochemical activity for the Hydrogen Evolution Reaction (HER) with small overpotentials of + 195 and + 325 mV at + 10 and + 100 mAcm− 2, respectively, and a low Tafel slope of 53.3 mV dec− 1 in seawater. Additionally, the electrocatalyst exhibited good stability after 72 h operation under a constant potential of -1.9 V vs. RHE. The efficient HER performance of the as-prepared catalyst was found to originate from the synergy between the conducting polymer and three-dimensional nickel nanoparticles with a large electrochemical active surface area. Moreover, the results obtained from electrochemical impedance spectroscopy (EIS) measurements revealed that the presence of 3D-Ni layer improved the kinetics of HER by reducing the charge transfer resistance for the electrocatalyst.

“…To elucidate the impact of electron transfer and conductivity, the electrochemical impedance spectroscopy (EIS) curve was examined at a measurement voltage of 1.55 V, as depicted in Figure 3f. In this analysis, the intersection points on the x-axis represent the solution resistance (R s ), which indicates the resistance between the working and reference electrodes [46,47]. The radius of the semicircle in the EIS curve corresponds to the charge transfer resistance (R ct ), representing the rate-determining step during the OER process.…”

The oxygen evolution reaction (OER) is a slow step in electrocatalytic water splitting. NiFe layered double hydroxides (LDH) have shown promise as affordable OER electrocatalysts, but their performance is hindered by poor charge transfer and sluggish kinetics. To address this, we doped NiFe LDH with sulfur (S) using an in situ electrodeposition method. By growing S-doped NiFe LDH on Cu nanoarrays, we created core–shell structures that improved both the thermodynamics and kinetics of OER. The resulting S-NiFe LDH@Cu core–shell nanoarrays exhibited enhanced activity in water oxidation, with a low potential of 236 mV (at 50 mA cm−2) and a small Tafel slope of 50.64 mV dec−1. Moreover, our alkaline electrolyzer, based on these materials, demonstrated remarkable activity, with a low voltage of 1.56 V at 100 mA cm−2 and excellent durability. The core–shell nanoarray structures provided a larger electroactive surface area, facilitated fast electron transport, and allowed for effective gas release. These findings highlight the potential of S-NiFe LDH@Cu core–shell nanoarrays as efficient OER electrocatalysts.
