P-doped CoCu aerogel as a bifunctional electrocatalyst for efficient overall water splitting

Co@Ir core–shell nanochain aerogels for the hydrogen evolution reaction and the oxygen evolution reaction in alkaline media

“…31,46 Moreover, the Ir 7 Co 3 aerogel exhibits the best performance in the series and its performance is also superior to those of recently reported high-level HER electrocatalysts (Table S1, ESI†). 14,31,32,35,47,48 Electrochemical impedance spectroscopy (EIS) measurements were then employed to probe the charge transfer behavior at the electrode and electrolyte interface. The EIS spectra are presented in Fig.…”

Phosphorus‐Modified Amorphous High‐Entropy CoFeNiCrMn Compound as High‐Performance Electrocatalyst for Hydrazine‐Assisted Water Electrolysis

“…This result confirms the important role of P‐modification in regulating the performance of high‐entropy catalysts. According to the previously reported work, [ 47,48 ] the modification of P‐anions contributes to regulating the electronic structure and adsorption free energy of reaction intermediates on the catalyst surface, resulting in greatly improved catalytic activity.…”

Oxygen deficient yolk–shell structured Co3O4 microspheres as an oxygen evolution reaction electrocatalyst for anion exchange membrane water electrolyzers

“…The ECSA was then calculated by using the following equation: ECSA = C dl / C s , where C s was 40 μF cm −2 . 22 Electrochemical impedance spectroscopy (EIS) analysis was performed at 1.68 V vs. RHE from 100 kHz to 1 Hz with an amplitude of 10 mV. The durability test was performed at a constant current density of 10 mA cm −2 for 16 h.…”
