Jun 11, 2024 · Ru–O covalency of the catalysts reflects the Ru-*OH bonding interaction, suggesting an optimal Ru–O covalency that is neither too weak nor too strong is favorable for OER.

Ruthenium(IV) oxide is the inorganic compound with the formula Ru O 2. This black solid is the most common oxide of ruthenium. It is widely used as an electrocatalyst for producing chlorine, chlorine oxides, and O 2. [1] Like many dioxides, RuO 2 adopts the rutile structure. [2] [3]

Apr 12, 2019 · High-resolution scanning transmission electron microscope (HR-STEM) and X-ray absorption spectroscopy (XAS) proved the singly dispersed state of atomic Ru, which was anchored on the surface of...

Jan 10, 2025 · In PEMWE, the resulting (RuIr)O 2 /C electrocatalysts demonstrate notable current density of 4.96 A cm −2 and mass activity of 19.84 A mg Ru+Ir−1 at 2.0 V.

Mar 13, 2025 · Here, we present a precise strategy to selectively activate the metal redox process while suppressing the undesired oxygen redox pathway by fine-tuning the Ru-O coordination number in amorphous RuOx.

Dec 13, 2024 · Ruthenium oxide (RuO 2) is a promising alternative because of its high activity, but its low durability has led to research on enhancing performance through heteroatom incorporation. The effects of incorporation quantity are unclear, leading to inconsistent results across studies using the same element.
