The transient covering of iridium species with ultrathin carbon shells via Joule-heating for robust acidic water oxidation

“…S40, ESI†). 49,50 These observations strongly indicated that the CIr-RJH-30 has excellent structural stability for practical applications in water electrolyzers.…”

Hydrogen oxidation electrocatalysts for anion-exchange membrane fuel cells: activity descriptors, stability regulation, and perspectives

“…122,232,233 In the design of hydrogen oxidation catalysts, it is imperative to address Ni oxidation. 234,235 A common strategy involves regulating the electronic structure of Ni through coupling and core-shell structures, reducing its electron cloud density to weaken its binding energy with oxygen, and thereby enhancing its oxidation potential. 236,237 3.2.2.…”

Single-atom sites combined with metal nano-aggregates for efficient electrocatalysis

“…65 The electrochemical in situ reconstruction is a dynamic process in which the physicochemical properties of the prepared catalysts undergo reversible/irreversible alterations while redefining the active components in the catalysts, thus affecting the catalytic performance. 66 Therefore, the construction or optimization of MNA–SACs is possible through the purposeful execution of electrochemical in situ reconfigurations.…”
