“…17,18 Therefore, it is important to develop new active as well as durable catalyst for acidic HER/HOR. On the other hand, alkali exchange membrane fuels (AEMFCs) and alkali membrane electrolyzers (AEMELs) are considered as an affordable alternative to PEMFCs and PEMELs because non-precious ORR 19,20 and OER [21][22][23][24] catalysts for alkaline media are available. Like acid media, Pt is also a good catalyst for alkaline HOR/HER.…”

Summary The development of new catalysts for Hydrogen evolution reaction/Hydrogen oxidation reaction (HER/HOR) is of crucial importance for the commercialization of Proton‐exchange membrane/Anion‐exchange membrane‐based renewable technologies. The sluggish HER/HOR kinetic (in base) and poor HER/HOR stability (in acid) of commercial Pt/C are the main obstacles. Interface engineering in multi‐component nanostructures is a method for enhanced electrochemical performances. We report interfaces‐engineered RuO2‐Pt/C as a pH‐independent catalyst for Hydrogen oxidation reaction/Hydrogen evolution reaction applications. The Hydrogen oxidation reaction/Hydrogen evolution reaction activity of RuO2‐Pt/C is one order magnitude higher than commercial Pt/C in base and 2.5‐fold higher in acid. It shows excellent stability in acid and base. It exhibits excellent pH tolerant HOR behavior. The i0,m of RuO2‐Pt/C in the base is ~1833 A.g−1RuPt which is 8‐fold higher than commercial Pt/C. The RuO2 in RuO2‐Pt/C makes it more active toward HER/HOR in base. Although it has similar activity in acid, its basic activity is 29‐fold higher than Ru‐Pt‐NPs/C. Hydrogen binding energy and OH binding energy are two equivalent descriptors for HOR/HER in base. HOR/HER activity of this catalyst in different 0.1 M electrolyte decreases in the sequence of Li+ > Na+ > K+ but improved HER and decreased HOR is observed with increasing Li+ ions. The [(H2O)x‐AM+‐(OH)ad] in double‐layer influences HOR/HER performance of RuO2‐Pt/C. This catalyst has great potential for application in PEM/AEM‐based devices.
