A RuO2IrO2 electrocatalyst with an optimal composition and novel microstructure for oxygen evolving in the single cell

Phosphorus doping of nickel–cobalt boride to produce a metal–metalloid–nonmetal electrocatalyst for improved overall water splitting

“…The electrochemical industry has continuously sought to develop low-cost materials with high catalytic activity to replace expensive noble-metal-based electrodes and thus reduce production overhead. [1][2][3][4] Electrochemical water splitting is one of the most efficient strategies available to produce hydrogen, which can be used as a form of storage for renewable electricity. Water electrolyzers that split water with the hydrogen evolution reaction (HER) at the cathode and the oxygen evolution reaction (OER) at the anode have attracted attention for use in energy conversion because they produce hydrogen fuel in an environmentally benign and highly efficient manner.…”

Preparation of NiFeCoMnCr Hydroxide on Nickel Foam by Corrosion Method and its Enhanced Electrochemical Performance in Oxygen Evolution Reaction

“…Thus, developing effective catalysts to enhance OER e ciency is critical. Noble metal-based catalysts, such as IrO 2 and RuO 2 , demonstrate high catalytic activity [5,6]; however, their scarcity, high cost, and low stability impede widespread commercialization [7].…”

Transition metal-doped V-shaped RuO2 103 nanotwins as highly active electrocatalysts for enhanced oxygen evolution in acidic media

“…To address this issue, the design and enhancement of Ru-based catalysts with high activity and stability is crucial. Previous studies have shown that adjusting the catalyst composition and structure can enhance OER catalytic activity [9][10][11][12]. The incorporation of transition metal doped (such as Fe, Co, Ag, etc), oxygen vacancy defects, and twin grain boundaries has been shown to effectively enhance the catalytic activity of OER [13][14][15][16][17][18][19][20].…”
